commit-graph: close_commit_graph before shallow walk
Call close_commit_graph() when about to start a rev-list walk that
includes shallow commits. This is necessary in code paths that "fake"
shallow commits for the sake of fetch. Specifically, test 351 in
t5500-fetch-pack.sh runs
git fetch --shallow-exclude one origin
with a file-based transfer. When the "remote" has a commit-graph, we do
not prevent the commit-graph from being loaded, but then the commits are
intended to be dynamically transferred into shallow commits during
get_shallow_commits_by_rev_list(). By closing the commit-graph before
this call, we prevent this interaction.
