When the allocation process is scheduled back and the mapped hw queue is changed, do one extra wake up on orignal queue for compensating wake up miss, so other allocations on the orignal queue won't be starved.
This patch fixes one request allocation hang issue, which can be triggered easily in case of very low nr_request.
