Felix Maurer 61d06f01f9 selftests: bpf: Check bpf_msg_push_data return value
bpf_msg_push_data may return a non-zero value to indicate an error. The
return value should be checked to prevent undetected errors.

To indicate an error, the BPF programs now perform a different action
than their intended one to make the userspace test program notice the
error, i.e., the programs supposed to pass/redirect drop, the program
supposed to drop passes.

Fixes: 84fbfe026a ("bpf: test_sockmap add options to use msg_push_data")
