[SCSI] mpt2sas: Corrected conditional checks for Internal device Reset

bug fix in the handling of the internal device reset event
The reason code check in scsih_sas_device_status_change_event never
evaluates as true for internal device reset, hence driver never quiesce s IO
when firmware is sending a device reset. The fix is to change the
evaluate to:
if (event_data->ReasonCode !=
    MPI2_EVENT_SAS_DEV_STAT_RC_INTERNAL_DEVICE_RESET &&
   event_data->ReasonCode !=
    MPI2_EVENT_SAS_DEV_STAT_RC_CMP_INTERNAL_DEV_RESET)
        return;
