[PATCH 02/11] midx.c: don't leak MIDX from verify_midx_file

[Taylor Blau <me@ttaylorr.com>]

The function midx.c:verify_midx_file() allocate a MIDX struct by calling
load_multi_pack_index(). But when cleaning up, it calls free() without
freeing any resources associated with the MIDX.

Call the more appropriate close_midx() which does free those resources,
which causes t5319.3 to pass when Git is compiled with SANITIZE=leak.
