Merge tag 'mkp-scsi-postmerge' of git://git.kernel.org/pub/scm/linux/kernel/git/mkp/scsi

Pull scsi fixes from Martin Petersen:
 "These two commits were in a separate postmerge branch due to a
  dependency on changes merged for 5.4 in the block tree.

  They fix two issues in the intersection of the request cleanup changes
  from block (b7e9e1fb7a) and the request batching changes
  (8930a6c207) that were made to SCSI during the 5.4 cycle"

* tag 'mkp-scsi-postmerge' of git://git.kernel.org/pub/scm/linux/kernel/git/mkp/scsi:
  scsi: core: fix dh and multipathing for SCSI hosts without request batching
  scsi: core: fix missing .cleanup_rq for SCSI hosts without request batching
