scsi: hisi_sas: Reset controller for internal abort timeout

Browse source

If an internal task abort timeout occurs, the controller has developed a
fault, and needs to be reset to be recovered. However if a timeout occurs
during SCSI error handling, issuing a controller reset immediately may
conflict with the error handling.

To handle internal abort in these two scenarios, only queue the reset when
not in an error handling function. In the case of a timeout during error
handling, do nothing and rely on the inevitable ha nexus reset to reset the
controller.
