Fix sporadic crash in QXcbScreen::getOutputProperty()
Although [0] claims "This request does never generate any errors", it
seems I sometimes get back a NULL pointer from
xcb_randr_get_output_property_reply(), leading to a segfault (in the
qdatetimeedit auto-test). So check reply isn't NULL before
dereferencing it.
