Revert "usb: gadget: u_ether: Do not make UDC parent of the net device"

Browse source 
This reverts commit 321b59870f.

This commit broke USB networking on Ingenic SoCs and maybe elsewhere.
The actual reason is unknown; and while a proper fix would be better,
we're sitting at -rc7 now, so a revert is justified - and we can work on
re-introducing this change for 6.3.
