[PATCH v3 5/7] refs: drop force_create argument of create_reflog API

["Han-Wen Nienhuys via GitGitGadget" <gitgitgadget@gmail.com>]

From: Han-Wen Nienhuys <hanwen@google.com>

There is only one caller, builtin/checkout.c, and it hardcodes
force_create=1.

This argument was introduced in abd0cd3a301 (refs: new public ref function:
safe_create_reflog, 2015-07-21), which promised to immediately use it in a
follow-on commit, but that never happened.
