files-backend: drop refs parameter from split_symref_update()

peff · gitster · commit 10dee40ed3f6 · 2019-02-14T15:26:15.000-08:00
This parameter was added in fcc42ea (split_symref_update(): add a files_ref_store argument, 2016-09-04) without comment, but never used. The splitting is purely mechanical, and doesn't depend on the particular ref-store. Let's drop this parameter in the name of simplicity.
