avfilter_init_str() already contains a log message about ignored stuff;
but it is currently dead code, because process_options() errors out if
it encounters an unknown option. That way only the first unrecognized
option will be printed.

This patch meanwhile is not about ignoring stuff at all; instead it
rejects (i.e. errors out) shorthand options after a non-shorthand option
has been encountered.
