USB: serial: omninet: fix reference leaks at open

Browse source 
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.

Fixes: 4a90f09b20 ("tty: usb-serial krefs")
