[PATCH v2 3/6] reflog-walk.c: use string_list_init_dup()

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

Change init_reflog_walk() to use the helper function added in
183113a5ca9 (string_list: Add STRING_LIST_INIT macro and make use of
it., 2010-07-04) rather than assuming that the "struct string_list"
part of "struct reflog_walk_info" can be memset() to 0, followed by
flipping ".strdup_strings = 1".

As explained in a preceding commit that can be assumed now if we peek
behind the guts of the "struct string_list", but there's no reason to
break the encapsulation here.

This does not match the newly added "struct string_list" rule for
changing CALLOC_ARRAY() followed by ".strdup_strings = 1" to
"ALLOC_ARRAY()" and "string_list_init_dup()" because here the
"CALLOC_ARRAY()" is allocating more than just the "struct
string_list".
