Well actually in case of failure of avfilter_init_filter() the
uninit() is not called, unless I'm looking in the wrong place.

I suppose the best way to fix it is to call uninit in
avfilter_init_filter(), or require the user to explicitly call
uninit() on the failing filter. Filters are inconsistent in this
regard (most of them keep allocated stuff in case of failure).
