ACK+cmnt: [PATCH] Revert "scsi: core: Cap scsi_host cmd_per_lun at can_queue"

[Kamal Mostafa]

Acked-by: Kamal Mostafa <kamal at canonical.com>

I think this patch title should be prefaced with "UBUNTU: SAUCE:" since
this revert is Ubuntu-specific.  The commit and code it reverts still exists
in upstream mainline and stables v4.15 and v4.19.
