pack-bitmap: drop bitmap_index argument from try_partial_reuse() 

Starting in commit 0f533c7284 (pack-bitmap: read multi-pack bitmaps,
2021-08-31), we no longer look at the "struct bitmap_index" passed to
try_partial_reuse(). This is because we only handle verbatim reuse from
a single pack: either the pack whose bitmap we're looking at, or the
"preferred" pack of a midx bitmap. And thus the primary item we look at
is the "pack" parameter added by that same commit, and not the
bitmap_git->pack parameter (which would be NULL for a midx bitmap). It's
our caller, reuse_partial_packfile_from_bitmap(), which decides which
pack to use and passes it in to us.

Drop the unused parameter to prevent confusion.
