usb: gadget: midi2: Fix missing UMP group attributes initialization
commit 21d8525d2e061cde034277d518411b02eac764e2 upstream.
The gadget card driver forgot to call snd_ump_update_group_attrs()
after adding FBs, and this leaves the UMP group attributes
uninitialized. As a result, -ENODEV error is returned at opening a
legacy rawmidi device as an inactive group.
This patch adds the missing call to address the behavior above.
