[GIT PULL 2/2] libata changes for v4.18-rc1

[Tejun Heo]

Hello, Linus.

This is the second part of libata pull request.

* libata has always been limiting the maximum queue depth to 31, 1 set
  aside mostly for historical reasons.  This didn't use to make much
  difference but Jens found out that modern hard drives can actually
  perform measurably better with the extra one queue depth.  Jens
  updated libata core so that it can make use of full 32 queue depth.

* Damien updated command retry logic in error handling so that it
  doesn't unnecessarily retry when upper layer (SCSI) is gonna handle
  them.

* A couple misc changes.

Thanks.
