midx.c: don't leak MIDX from verify_midx_file

The function midx.c:verify_midx_file() allocates 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.
