ath10k: use workqueue to set WEP TX key

Browse source

Recent WMI/HTC changes made it possible for WMI
commands to sleep (if there's not enough HTC TX
credits to submit a command). TX path is in an
atomic context so calling WMI commands in it is
wrong.

This simply moves WEP key index update to a worker
and fixes the 'scheduling while atomic' bug.

This still leaves multiple WEP key handling laggy,
i.e. some frames may be TXed with an old/different
key (although recipient should still be able to RX
them).
