This patch tweats the socket_bind bpf prog to test the
local_storage->smap == NULL case in the bpf_local_storage_free()
code path. The idea is to create the local_storage with
the sk_storage_map's selem first. Then add the sk_storage_map2's selem
and then delete the earlier sk_storeage_map's selem.
