list-objects-filter: don't memset after releasing filter struct

If we see an error while parsing a "combine" filter, we call
list_objects_filter_release() to free any allocated memory,
and then use memset() to return the struct to a known state. But the
release function already does that reinitializing. Doing it again is
pointless.
