console/dummy: leave .con_font_get set to NULL
commit 724ba8b30b044aa0d94b1cd374fc15806cdd6f18 upstream. When this method is set, the caller expects struct console_font fields to be properly initialized when it returns. Leave it unset otherwise nonsensical (leaked kernel stack) values are returned to user space.
