get_patch_filename(): drop "just-numbers" hack

The function chooses from three operating modes (format using the
subject, the commit, or just number) based on NULL-ness of two of
its parameters, which is an ugly hack for sharing only a bit of
code.

Separate out the "just numbers" part out to the callers.
