Subject: vo: don't crash when changing panscan before first configuration

When the VO was not initialized with vo_reconfig(), or if the last
vo_reconfig() failed, changing panscan would cause a crash due to
vo_get_src_dst_rects() dereferencing vo->params (NULL if not
configured).

Just do nothing if that happens, as there is no video that could be
displayed anyway.
