locking: Remove spin_unlock_wait() generic definitions

Browse Source 
There is no agreed-upon definition of spin_unlock_wait()'s semantics,
and it appears that all callers could do just as well with a lock/unlock
pair.  This commit therefore removes spin_unlock_wait() and related
definitions from core code.
