commit-graph: avoid malloc'ing a local variable

We do need a context to write the commit graph, but that context is only
needed during the life time of `commit_graph_write()`, therefore it can
easily be a stack variable.

This also helps CodeQL recognize that it is safe to assign the address
of other local variables to the context's fields.
