Jaroslav Kysela 9ab3696881 ALSA: control-led: use strscpy in set_led_id() ...

commit 70051cffb31b5ee09096351c3b41fcae6f89de31 upstream.

The use of strncpy() in the set_led_id() was incorrect.
The len variable should use 'min(sizeof(buf2) - 1, count)'
expression.

Use strscpy() function to simplify things and handle the error gracefully.
