seqlock: consolidate spin_lock/unlock waiting with spin_unlock_wait
since c2f21ce ("locking: Implement new raw_spinlock")
include/linux/spinlock.h includes spin_unlock_wait() to wait for a concurren
holder of a lock. this patch just moves over to that API. spin_unlock_wait
covers both raw_spinlock_t and spinlock_t so it should be safe here as well.
the added rt-variant of read_seqbegin in include/linux/seqlock.h that is being
modified, was introduced by patch:
seqlock-prevent-rt-starvation.patch
behavior should be unchanged.
