USB: pl2303: fix use-after-free in TIOCMIWAIT

commit 40509ca982c00c4b70fc00be887509feca0bff15 upstream.

Use the port wait queue and make sure to check the serial disconnected
flag before accessing private port data after waking up.

This is is needed as the private port data (including the wait queue
itself) can be gone when waking up after a disconnect.
