dm vdo data-vio: silence sparse warnings about locking context imbalances
Factor wait_permit() out from acquire_permit() so that the latter
always holds the spinlock and the former always releases it.
Otherwise sparse complains about locking context imbalances due to
conditional spin_unlock in acquire_permit:
warning: context imbalance in 'acquire_permit' - different lock contexts for basic block
warning: context imbalance in 'vdo_launch_bio' - unexpected unlock
