Takashi Iwai 306f3f78a5 ALSA: control: Keep the previous numid at snd_ctl_rename_id() ...

We don't need to change the numid at each time snd_ctl_rename_id() is
called, as the control element size itself doesn't change.  Let's keep
the previous numid value.

Along with it, add a note about calling this function only in the
card init phase.
