[PATCH 4.9 13/44] usb: bdc: change state when port disconnected

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

From: Justin Chen <justinpopo6@gmail.com>

commit fb8f60dd1b67520e0e0d7978ef17d015690acfc1 upstream.

When port is connected and then disconnected, the state stays as
configured. Which is incorrect as the port is no longer configured,
but in a not attached state.
