This patch fixes a possible null pointer dereference in
do_load, detected by the semantic patch deref_null.cocci,
with the following warning:
./tools/bpf/bpftool/prog.c:1021:23-25: ERROR: map_replace is NULL but dereferenced.
The following code has potential null pointer references:
881 map_replace = reallocarray(map_replace, old_map_fds + 1,
882 sizeof(*map_replace));
883 if (!map_replace) {
884 p_err("mem alloc failed");
885 goto err_free_reuse_maps;
886 }
...
1019 err_free_reuse_maps:
1020 for (i = 0; i < old_map_fds; i++)
1021 close(map_replace[i].fd);
1022 free(map_replace);
