Andrey Konovalov 6c0fa0936a ALSA: usb-audio: avoid freeing umidi object twice
commit 07d86ca93d upstream.

The 'umidi' object will be free'd on the error path by snd_usbmidi_free()
when tearing down the rawmidi interface. So we shouldn't try to free it
in snd_usbmidi_create() after having registered the rawmidi interface.
