Stanislav Fomichev 92f24f98d5 bpf: Clarify error expectations from bpf_clone_redirect
[ Upstream commit 7cb779a686 ]

Commit 151e887d8f ("veth: Fixing transmit return status for dropped
packets") exposed the fact that bpf_clone_redirect is capable of
returning raw NET_XMIT_XXX return codes.

This is in the conflict with its UAPI doc which says the following:
"0 on success, or a negative error in case of failure."

Update the UAPI to reflect the fact that bpf_clone_redirect can
return positive error numbers, but don't explicitly define
their meaning.
