block: move q->unplug_work initialization
modprobe loop; rmmod loop effectively creates a blk_queue and destroys it
which results in q->unplug_work being canceled without it ever being
initialized.
Therefore, move the initialization of q->unplug_work from
blk_queue_make_request() to blk_alloc_queue*().
