3.5.7.28 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Michael Grzeschik <m.grzeschik@pengutronix.de>

commit 2bac51a1827a18821150ed8c9f9752c02f9c2b02 upstream.

The delayed_status value is used to keep track of status response
packets on ep0. It needs to be reset or the set_config function would
still delay the answer, if the usb device got unplugged while waiting
for setup_continue to be called.
