usb: gadget: qdss: Fix usage of usb_ep_autoconfig()

commit 59ff8848 ("usb: gadget: qdss: Use usb_ep_autoconfig()
instead of ss() variant") modified f_qdss to use the simple
usb_ep_autoconfig() helper, however this function has a caveat
that the passed in descriptor's wMaxPacketSize field gets updated
to be a maximum to 64 bytes. Hence, this function should not be
called with descriptors intended for high- or Superspeed usage
since they can support up to 512 or 1024 bytes for bulk endpoints.

Instead, call usb_ep_autoconfig() by passing in the FS descriptors,
and use the resulting bEndpointAddress assignment to update the
corresponding HS and SS descriptors.
