Subject: [PATCH v2 00/11] scsi_debug: Some minor improvements

This series contains a bunch of minor improvements to the driver. I have
another bunch waiting with more major changes.

Most of the changes are quite straightforward, and the only patches of note are
as follows:
- Fix the command abort feature, enabled with host option SDEBUG_OPT_CMD_ABORT
- Drop driver count of queued commands per device
- Add poll mode completions to statistics. We already have poll mode callback
  call count, so maybe it was intentional to omit poll mode from the
  statistics.
  
Difference to v1:
- rename function to get sdebug host from shost (Bart)

Based on scsi-staging 6.4 @ commit 0b31b77f281a ("Merge patch series "PCI/AER: ...")
