scan-tree: fix error caused by missing parameter name

This fixes an error which was introduced by
2f50b47c72cbc4270bbd12ae7f520486d5f42736. Git 2.42.0 added a new argument
to config_fn_t, and it was added to gitconfig_config(), but not named.
This causes compile warnings/errors. This commit fixes that by naming the
new parameter, and marking it unused.
