ALSA: usb-audio: Use snd_ctl_rename() to rename a control

commit 0b4f0debb34754002cee295441c9ca89ba8cdfcc upstream.

With the recent addition of hashed controls lookup it's not enough to just
update the control name field, the hash entries for the modified control
have to be updated too.

snd_ctl_rename() takes care of that, so use it instead of directly
modifying the control name.
