Log Message:
Use two different mutexes for tx and rx

This change splits the mutex of wm into two: one for tx and the other
for rx. By doing so, lock contentions can be reduced. We lock both for
other operations that need locking, e.g., init, stop and ioctl.

The modification doesn't change the behavior of the driver.
