Johan Hovold b91cfb2573 tty: mxser: fix TIOCSSERIAL permission check ...

Changing the port type and closing_wait parameter are privileged
operations so make sure to return -EPERM if a regular user tries to
change them.

Note that the closing_wait parameter would not actually have been
changed but the return value did not indicate that.
