Takashi Iwai 473e554d65 scsi: gdth: Use scnprintf() for avoiding potential buffer overflow ...

Since snprintf() returns the would-be-output size instead of the actual
output size, the succeeding calls may go beyond the given buffer limit.
Fix it by replacing with scnprintf().

[mkp: checkpatch fix]
