[PATCH] fill_oids_from_packs: fix memory leak when fill_oids_from_packs failed

["Lidong Yan via GitGitGadget" <gitgitgadget@gmail.com>]

From: Lidong Yan <502024330056@smail.nju.edu.cn>

In commit-graph.c line 1930, if open_pack_index failed, memory allocated
in line 1925 by add_packed_git will leak. Simply add close_pack and
free(p) will solve this problem.
