The carl9170_op_ampdu_action() function is used only by the mac80211
framework.
Since the mac80211 already takes care of checks and properly serializing
calls to the driver's function there is no need for the driver to do the same
thing.

This patch ensures that the module parameter "use_chanctx" is
visible only when CONFIG_ATH9K_CHANNEL_CONTEXT is selected.
Also register the channel context callbacks with mac80211 only
when it is explicitly enabled and compile them out of the driver
when CONFIG_ATH9K_CHANNEL_CONTEXT is not selected.

Add the missing null termination after strncpy().
This isn't actually a buffer overflow in this case since we use
snprintf() appropriately to fill the buffer passed by the caller,
but in the interest of not turning this into a bug down the road,
go ahead and force termination here.

While updating 'left_len' in each iteration, we should subtract
last TLV length not the accumulated length of TLVs parsed till
now.
This bug in parsing logic is exposed by newer firmware which adds
two TLVs in GET_HW_SPEC command response. Earlier firmwares used to
add only one TLV.

Based on a quick test with AR9271, TDLS seems to be working fine.
Tests were done with 2 Atheros AR9271 based devices with firmware
1.3 (sha1 8d49f928aa40ac53c729189bff1333cd373a7fb5), associated
with a WAP54G access point. TDLS worked fine both in WPA2 mode and
without encryption. Stations maintained ping flood traffic between
each other and towards the AP without significant losses.
Not tested with AR7010.
TDLS was enabled in earlier patches the same way for other
Atheros drivers:
ath9k (fd6562344dea2b8b2a5d644cf971f4e56004500a),
and carl9170 (d1f3de71a584a82ee4e84505fce9acccf40215ff).

see the following:

It was possible on a host system running low on
memory to end up with no rx buffers on pci pipes.
This makes the driver more robust as it won't fail
to start if it can't allocate all rx buffers right
away. If it is fatal then upper layers will notice
trouble anyway.

This fixes two corner cases.
One is a race between disabling copy engine
interrupts and unhandled pending interrupts on the
host. This could end up with a runaway tasklet and
consequently memory leak of a few copy engine
rx buffers.
The other one is an unexpected (and non-maskable
via device CSR) MSI fw indication interrupt during
teardown. This could trigger the same problem as
the first corner case.

If spectral is unregistered after mac80211, the relayfs file has already
been removed recursively by mac/cfg80211, and spectral tries to remove
the file once more, thus leading to double free problems. Better clean
up spectral before to avoid that problem.
