bpf: Improve verifier log for resource leak on exit
[ Upstream commit cbd8730aea8d79cda6b0f3c18b406dfdef0c1b80 ]
The verifier log when leaking resources on BPF_EXIT may be a bit
confusing, as it's a problem only when finally existing from the main
prog, not from any of the subprogs. Hence, update the verifier error
string and the corresponding selftests matching on it.
