block: Schedule runtime resume earlier
Instead of scheduling runtime resume of a request queue after a request has been queued, schedule asynchronous resume during request allocation. The new pm_request_resume() calls occur after blk_queue_enter() has increased the q_usage_counter request queue member. This change is needed for a later patch that will make request allocation block while the queue status is not RPM_ACTIVE.
