mpt_HardResetHandler — Generic reset handler
Pointer to MPT_ADAPTER structure
Indicates if sleep or schedule must be called.
Issues SCSI Task Management call based on input arg values. If TaskMgmt fails, returns associated SCSI request.
_HardResetHandler can be invoked from an interrupt thread (timer) or a non-interrupt thread. In the former, must not call schedule.
A return of -1 is a FATAL error case, as it means a FW reload/initialization failed.
Returns 0 for SUCCESS or -1 if FAILED.
