wlan: Change RX wakelock to 50 milliseconds

When the original change to add wakelock to the RX path was added, we
intended to use only 50 milliseconds. However msecs_to_jiffies() were
not added to the timeout argument; so later when the API was corrected
it was considered as 500 milliseconds. Restore the original intended
value.
