last-modified: keep per-path Bloom filters for wildcard pathspecs
The last-modified builtin expands the pathspec to a set of literal paths and builds a Bloom key for each. During the walk it looks those keys up in the commit's filter to decide whether the commit is worth diffing. These lookups need `bloom_filter_settings` for the key hashing. prepare_revision_walk() runs prepare_to_use_bloom_filter() to build the pathspec key vectors. For a pathspec that cannot be turned into a Bloom key, such as a top-level wildcard like "*.c", that function gives up and clears `bloom_filter_settings`. Restore `bloom_filter_settings` after prepare_revision_walk() so the per-path check keeps working for wildcard pathspecs.
