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.
