tty: goldfish: Use tty_port_destroy() to destroy port

[ Upstream commit 507b05063d1b7a1fcb9f7d7c47586fc4f3508f98 ]

In goldfish_tty_probe(), the port initialized through tty_port_init()
should be destroyed in error paths.In goldfish_tty_remove(), qtty->port
also should be destroyed or else might leak resources.

Fix the above by calling tty_port_destroy().
