commit 699412d951e6dd4dec48db88f33dc27b361582f0
Author: Felipe Balbi <ba...@ti.com>

usb: gadget: net22xx: fix ->disconnect reporting
with the latest udc_start/udc_stop conversion,
too much code was deleted which ended up creating
a regression in net2272 and net2280 drivers.
To fix the regression we revert one hunk of the
original commits.
