tty: Drop krefs for interrupted tty lock
commit e9036d0662360cd4c79578565ce422ed5872f301 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: 0bfd464d3fdd ("tty: Wait interruptibly for tty lock on reopen")
