usb: gadget: f_uac2: Fix incorrect setting of bNumEndpoints

Browse source

commit 057bd54dfc upstream.

Currently afunc_bind sets std_ac_if_desc.bNumEndpoints to 1 if
controls (mute/volume) are enabled. During next afunc_bind call,
bNumEndpoints would be unchanged and incorrectly set to 1 even
if the controls aren't enabled.

Fix this by resetting the value of bNumEndpoints to 0 on every
afunc_bind call.
