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.
