bisect: clear flags in passed repository

69d2cfe (bisect.c: remove the_repository reference, 2018-11-10) kept
the implicit the_repository reference in clear_commit_marks_all, which
was made explicit by the previous commit (and which also renamed it to
repo_clear_commit_marks).  Replace it as well.
