Subject: scsi: smartpqi: minor driver cleanup
Patch-mainline: v4.13-rc1
Git-commit: cbe0c7b11dbfda368f27a6935a08ba91522edf1a
References: bsc#1038125
- remove debug code that is no longer necessary.
- Some WARN_ON checks were removed because the driver continues
to function when the conditions are met.
- remove a MACRO that is no longer used.
- remove unnecessary multi-line statements.
