This patch continues where the previous commit:
"carl9170: fix async command buffer leak"
left off.
Similar to carl9170_reboot/carl9170_powersave, the
carl9170_async_regwrite* macros would leak the
temporary command buffer, if __carl9170_exec_cmd
fails to upload the command to the device.

The hardware rx-filter was essentially disabled, because
of a serve, yet unidentifiable problem with iwlagn.
Due to these circumstances the driver and mac80211 were
left with the job of filtering.
This is very unfortunate and has proven to be expensive
in terms of latency, memory and load.
Therefore the new 1.8.8.3 firmware introduces a flexible
filtering infrastructure which allows the driver to
offload some of the checks (FCS & PLCP crc check,
RA match, control frame filter, etc...) whenever possible.
Note:
This patch also includes all changes to the
shared headers files since the inclusion.
