locking/rwsem: Return void in __rwsem_mark_wake()
We currently return a rw_semaphore structure, which is the same lock we passed to the function's argument in the first place. While there are several functions that choose this return value, the callers use it, for example, for things like ERR_PTR. This is not the case for __rwsem_mark_wake(), and in addition this function is really about the lock waiters (which we know there are at this point), so its somewhat odd to be returning the sem structure.
