USB: serial: omninet: fix reference leaks at open
commit 30572418b445d85fcfe6c8fe84c947d2606767d8 upstream.
This driver needlessly took another reference to the tty on open, a
reference which was then never released on close. This lead to not just
a leak of the tty, but also a driver reference leak that prevented the
driver from being unloaded after a port had once been opened.
