scsi: gdth: avoid buffer overflow warning
gcc notices that we would overflow the buffer for the inquiry of the product name if we have too many adapters: drivers/scsi/gdth.c: In function 'gdth_next': drivers/scsi/gdth.c:2357:29: warning: 'sprintf' may write a terminating nul past the end of the destination [-Wformat-overflow=] sprintf(inq.product,"Host Drive #%02d",t); ^~~~~~~~~~~~~~~~~~~ drivers/scsi/gdth.c:2357:9: note: 'sprintf' output between 16 and 17 bytes into a destination of size 16 sprintf(inq.product,"Host Drive #%02d",t); This won't happen in practice, so just use snprintf to truncate the string.
