V3 changes
 - patch#2
  - Adjust tab indents for line continuation (Christoph's comment)

V2 changes
 - patch#1
  - use blk_mq_complete_request_remote() instead of blk_mq_set_request_complete()

 - patch#2
  - Modify patch based on the patch#1 v2 changes.
  - Use iob.complete(&iob) instead of virtblk_complete_batch(&iob)
    at virtblk_done() (Stefan's comment)
  - It shows almost same performance improvement as v1 patch.
