avfilter/f_metadata: do not return the frame early if there is no metadata

The early return caused isses for the "add" mode (got fixed in
c95dfe5cce98cde3e7fb14fbd04b3897f3927cec) and the "select" mode needs a similar
fix. It is probably better to fully remove the check, since all modes work
correctly with NULL metadata.
