usb: gadget: f_uac2: fix build warning

Browse Source 
commit 913e4a90b6f9 ("usb: gadget: f_uac2:
finalize wMaxPacketSize according to bandwidth")
added a possible build warning when calling
min(). In order to fix the warning, we just
make sure to call min_t() and tell that its
arguments should be u16.
