Luis R. Rodriguez 7583c550c3 ath9k: add locking for starting the PCU on RX
There was some locking for starting some parts of
RX but not for starting the PCU. Include this otherwise
we can content against stopping the PCU.

This can potentially lead to races against different
buffers on the PCU which can lead to to the DMA RX
engine writing to buffers which are already freed.

This is part of a series that will help resolve the bug:
