[PATCH -next] ALSA: gus: Replace unsafe strcpy() with strscpy()

[YueHaibing]

Fix smatch warning:
sound/isa/gus/gus_main.c:396 snd_gus_check_version() error:
 strcpy() 'card->longname' too large for 'card->shortname' (80 vs 32)

Even if this is not a real bug since the longest length of card->longname
now is 31, replace strcpy() with strscpy() in order to avoid possible
future mistake.
