Subject: ALSA: usb-audio: avoid freeing umidi object twice
From: Andrey Konovalov <andreyknvl@xxxxxxxxx>
commit 07d86ca93db7e5cdf4743564d98292042ec21af7 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.
Found by KASAN.
