[patch 16/18] net/airo: replace schedule_timeout() with msleep()/msleep_interuptible()

[janitor@xxxxxxxxxxxxxx]

Any comments would be appreciated.

Description: Use msleep()/msleep_interruptible() [as appropriate]
instead of schedule_timeout() to guarantee the task delays as
expected. Also uses set_current_state() instead of direct assignment of
current->state in one place.
