usb: gadget: u_audio: Clear uac pointer when freed.
This prevents use of a stale pointer if functions are called after
g_cleanup that shouldn't be. This doesn't fix any races, but converts
a possibly silent kernel memory corruption into an obvious NULL pointer
dereference report.
Fixes: eb9fecb9e69b ("usb: gadget: f_uac2: split out audio core")
