Move the request complete logic out of blkif_interrupt() to a work queue, after that we can replace 'spin_lock_irq' with 'spin_lock' so that irq won't be disabled too long in blk_mq_queue_rq().
I think using a threaded interrupt (like scsifront) is better than work. Also, this seems orthogonal to the multiqueue support. Is it a useful bug fix on its own?
