list-objects-filter: plug combine_filter_data leak

rscharfe · gitster · commit 7c2dc122f919 · 2022-11-21T16:43:26.000+09:00
filter_combine__init() allocates a struct combine_filter_data object and
assigns it to the filter_data member of struct filter_options.  Release
it in the complementing filter_combine__free().
