[PATCH 06/10] reflog-walk.c: request allocated buffer from resolve_ref()

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

for_each_reflog_ent() can do anything, including calling resolve_ref()
again. Therefore it's not safe to use the static buffer returned by
resolve_ref(). Request it to allocate new buffer instead.
