scsi: Print command name in debug

Browse source 
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().
