usb: gadget: f_uac1_legacy: disable ep in f_audio_disable()

Browse Source 
The f_audio_disable() doesn't disable usb ep, and
this cause usb enumeration fail. So add usb ep
disable operation.

This patch also reinitializes the opts->bound flag
to false in f_audio_free(), and then it can setup
ALSA audio device again in f_audio_bind().
