carl9170: remove stale rx error path
The total/fatal error bit was erroneously prefixed
with AR9170_RX_ERROR instead of AR9170_RX_STATUS.
Luckily, the hardware specification confirmed that
the 0x80 flag will never be set for mac->error.
So, it was always just a dead branch.
This patch also imports the latest version of
shared wlan.h header from the firmware git.
