[NET]: Fix locking in shaper driver.
o use a semaphore instead of an opencoded and racy lock
o move locking out of shaper_kick and into the callers - most just
released the lock before calling shaper_kick
o remove in_interrupt() tests. from ->close we can always block, from
->hard_start_xmit and timer context never
