Instead of writing the name of the reflog file into a strbuf that is
supplied by the caller but not needed there, write it into a local
temporary buffer and remove the strbuf parameter entirely.
And while we're adjusting the function signature, reorder the arguments
to move the input parameters before the output parameters.
