usb: gadget: ether: Fix race between gether_disconnect and rx_submit
commit d29fcf7078bc8be2b6366cbd4418265b53c94fac upstream.
On spin lock release in rx_submit, gether_disconnect get a chance to
run, it makes port_usb NULL, rx_submit access NULL port USB, hence null
pointer crash.
Fixed by releasing the lock in rx_submit after port_usb is used.
