[PATCH v2 1/5] fetch: Rename max_children to max_children_for_submodules

[Palmer Dabbelt]

This does not change any functionality, but instead just prepares for
the upcoming "--fetch-jobs=<n>" support.  Essentially the "max_children"
variable is ambiguously named, which would complicate the diff in
squashed into the "--fetch-jobs=<n>" patch.
