Don Brace f749d8b7a9 scsi: hpsa: Correct dev cmds outstanding for retried cmds 
Prevent incrementing device->commands_outstanding for ioaccel command
retries that are driver initiated.  If the command goes through the retry
path, the device->commands_outstanding counter has already accounted for
the number of commands outstanding to the device.  Only commands going
through function hpsa_cmd_resolve_events decrement this counter.

 - ioaccel commands go to either HBA disks or to logical volumes comprised
   of SSDs.

The extra increment is causing device resets to hang.

 - Resets wait for all device outstanding commands to complete before
   returning.

Replace unused field abort_pending with retry_pending. This is a
maintenance driver so these changes have the least impact/risk.
