workqueue: mark lock acquisition on worker_maybe_bind_and_lock()

worker_maybe_bind_and_lock() actually grabs gcwq->lock but was missing proper
annotation. Add it. So this patch will remove following sparse warnings:

kernel/workqueue.c:1214:13: warning: context imbalance in 'worker_maybe_bind_and_lock' - wrong count at exit
arch/x86/include/asm/irqflags.h:44:9: warning: context imbalance in 'worker_rebind_fn' - unexpected unlock
kernel/workqueue.c:1991:17: warning: context imbalance in 'rescuer_thread' - unexpected unlock
