[PATCH 4/6] verify_one_sparse(): drop unused repository parameter

[Jeff King <peff@peff.net>]

This function has never used its repository parameter since it was
introduced in 9ad2d5ea71 (sparse-index: loose integration with
cache_tree_verify(), 2021-03-30). As that commit notes, it may
eventually be extended further, and that might require looking at a
repository struct. But it would be easy to add it back later if
necessary. In the mean time, dropping it makes the code shorter and
appease -Wunused-parameter.
