[PATCH] ALSA: ump: Use safe_append_string() in snd_ump_update_group_attrs()

[PATCH] ALSA: ump: Use safe_append_string() in snd_ump_update_group_attrs()

[Thorsten Blum]

To prepare for removing strlcat() from the kernel [1], use the existing
safe_append_string() helper to append the group name separator.

No functional change.
