mutex: Fix up mutex_waiter usage
The patch moving bits into mutex.c was a little too much; by also moving struct mutex_waiter a few less common CONFIGs would no longer build. Fixes: 5f35d5a66b3e ("locking/mutex: Make __mutex_owner static to mutex.c") Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org>
