Pratham Pratap 2fa89458af usb: gadget: f_uac2: Fix incorrect increment of bNumEndpoints 
Currently connect/disconnect of USB cable calls afunc_bind and
eventually increments the bNumEndpoints. Performing multiple
plugin/plugout will increment bNumEndpoints incorrectly, and on
the next plug-in it leads to invalid configuration of descriptor
and hence enumeration fails.

Fix this by resetting the value of bNumEndpoints to 1 on every
afunc_bind call.
