[PATCH] samples/bpf: Fix test_maps/bpf_get_next_key() test

[Michael Holzheu]

Looks like the "test_maps" test case expects to get the keys in
the wrong order when iterating over the elements:

test_maps: samples/bpf/test_maps.c:79: test_hashmap_sanity: Assertion
`bpf_get_next_key(map_fd, &key, &next_key) == 0 && next_key == 2' failed.
Aborted

Fix this and test for the correct order.
