[PATCH] remove wq_lock_t cruft
This patch removes the whole wq_lock_t abstraction, forcing the behavior
to be that of a standard spinlock and changes all the wq_lock code in
the tree appropriately.
Removes lots of code - always a Good Thing to me. New behavior is same
as previous behavior (USE_RW_WAIT_QUEUE_SPINLOCK unset).
