Peter Hurley cc04a14338 tty: Drop krefs for interrupted tty lock ...

commit e9036d0662 upstream.

When the tty lock is interrupted on attempted re-open, 2 tty krefs
are still held. Drop extra kref before returning failure from
tty_lock_interruptible(), and drop lookup kref before returning
failure from tty_open().

Fixes: 0bfd464d3f ("tty: Wait interruptibly for tty lock on reopen")
