Takashi Iwai 21d8525d2e usb: gadget: midi2: Fix missing UMP group attributes initialization 
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.
