Jiri Slaby (SUSE) 2299e3ba12 tty: introduce and use tty_port_tty_vhangup() helper 
[ Upstream commit 2b5eac0f8c ]

This code (tty_get -> vhangup -> tty_put) is repeated on few places.
Introduce a helper similar to tty_port_tty_hangup() (asynchronous) to
handle even vhangup (synchronous).

And use it on those places.

In fact, reuse the tty_port_tty_hangup()'s code and call tty_vhangup()
depending on a new bool parameter.
