[PATCH bpf-next v2 3/4] selftests/bpf: don't mask result of bpf_csum_diff() in test_verifier

[Puranjay Mohan]

The bpf_csum_diff() helper has been fixed to return a 16-bit value for
all archs, so now we don't need to mask the result.

This commit is basically reverting the below:

commit 6185266c5a85 ("selftests/bpf: Mask bpf_csum_diff() return value
to 16 bits in test_verifier")
