[PATCH v2] Pioneer devices: engage implicit feedback sync for playback

Dr. Iwai, here's the additional debugging information you asked for.
First dyndbg log is for successful engagement of implicit feedback sync on
the playback.
Second case I modified snd_usb_parse_implicit_fb_quirk to return 0 as it
would normally, unsuccessful.
Third is lsusb -v of Pioneer DJ DDJ-SR2.
I think I know now why we need to return 1 like a capture quirk was found
inside snd_usb_parse_implicit_fb_quirk: if we don't it triggers sync ep
code inside pcm.c
As always, thank you for your time.
