[PATCH v4 14/17] commit-graph: drop unnecessary `graph_read_bloom_data_context`

[Taylor Blau <me@ttaylorr.com>]

The `graph_read_bloom_data_context` struct was introduced in an earlier
commit in order to pass pointers to the commit-graph and changed-path
Bloom filter version when reading the BDAT chunk.

The previous commit no longer writes through the changed_paths_version
pointer, making the surrounding context structure unnecessary. Drop it
and pass a pointer to the commit-graph directly when reading the BDAT
chunk.
