This makes scsi_command_name() public. This makes use of scsi_command_name() in debug output for scsi-disk and spapr-vscsi host bus adapter. Before this, SCSI used to print hex numbers instead of human-friendly strings. This adds GET_EVENT_STATUS_NOTIFICATION and READ_DISC_INFORMATION to the list of SCSI commands supported by scsi_command_name().
