usb: gadget: f_uac2: disable IN/OUT ep if unused

Browse source

Via p_chmask/c_chmask the user can define whether uac2 shall support
playback and/or capture. This has only effect on the created ALSA device,
but not on the USB descriptor. This patch adds playback/capture descriptors
dependent on that parameter.
