[PATCH] Pass a lock expression to __cond_lock, like __acquire and __release

[PATCH] Pass a lock expression to __cond_lock, like __acquire and __release

Currently, __acquire and __release take a lock expression, but __cond_lock
takes only a condition, not the lock acquired if the expression evaluates
to true.  Change __cond_lock to accept a lock expression, and change all
the callers to pass in a lock expression.
