Bring over some more status codes from the Linux iwlwifi driver.

The (eventual) intention is to create MIB counters for transmitted
frame completion to count how many packets with each status are
transmitted.

Note the difference between A-MPDU and non A-MPDU status.

Obtained from:	Linux iwlwifi/dvm driver
