[PATCH 4/4] Clean: Remove useless parameters from both get_commit_info() functions

[Michael Witten <mfwitten@gmail.com>]

Both `builtin/blame.c' and `reflog-walk.c' have static get_commit_info()
functions:

    $ echo; git grep get_commit_info 7811d9600f02e70c9f835719c71156c967a684f7 | cut -c42-

    builtin/blame.c:static void get_commit_info(struct commit *commit,
    builtin/blame.c:	get_commit_info(suspect->commit, &ci, 1);
    builtin/blame.c:	get_commit_info(suspect->commit, &ci, 1);
    builtin/blame.c:			get_commit_info(suspect->commit, &ci, 1);
    reflog-walk.c:static struct commit_info *get_commit_info(struct commit *commit,
    reflog-walk.c:		get_commit_info(commit, &info->reflogs, 0);

Every time one of the get_commit_info() functions is called, the
last parameter is invariably set to the same constant, rendering that
parameter effectively useless.

This commit removes those last parameters and updates the function bodies
and calls accordingly.
