Takashi Iwai 877135c58a usb: gadget: midi2: Fix MIDI2 IN EP max packet size

commit 116e79c679 upstream.

The EP-IN of MIDI2 (altset 1) wasn't initialized in
f_midi2_create_usb_configs() as it's an INT EP unlike others BULK
EPs.  But this leaves rather the max packet size unchanged no matter
which speed is used, resulting in the very slow access.
And the wMaxPacketSize values set there look legit for INT EPs, so
let's initialize the MIDI2 EP-IN there for achieving the equivalent
speed as well.
