scsi: hisi_sas: add v2 hw slot complete internal abort support
Add code in slot_complete_v2_hw() to deal with the slots which have
completed due to internal abort.
The status codes have the following meaning:
- STAT_IO_ABORTED: the IO has been aborted due to internal abort,
whether by device or individual abort command
- STAT_IO_COMPLETE: internal abort command has completed successfully
for device or individual abort command
- STAT_IO_NO_DEVICE: internal abort command has completed for device but
cannot find any IO
- STAT_IO_NOT_VALID: internal abort command has completed for single
command but could not find the command
