[PATCH 1/7] net/9p/usbg: also disable endpoints on p9_usbg_close

[Michael Grzeschik <mgr@kernel.org>]

The close function has to fully reverse the state change of 9p_create
(mount) and the potential call of set_alt(1). This includes to ensure
that the usage of the endpoints is not active any more.
