carl9170: fix signal strength reporting issues
On A-MPDU frames, the hardware only reports valid
signal strength data for the last subframe.
This patch fixes it by flagging everything but the
last subframe in an A-MPDU to tell mac80211 to
ignore the signal strength entirely. Otherwise
the empty value (= 0 dbm) will distort the
average quite badly.
