UDP health check always returns true.
Any upstreams monitored with UDP don't accurately reflect the endpoints status.
Tested on v1.17.8

@idmaoning @veduco @ice2lin ：
The root cause is that I hadn't set default check data which cause the checker didn't send check packet.
I fixed it in this commit: 6188804
Please re-pull the master branch and re-compile & test it again if needed.
Anyway, thank you for you guys' feedback :D

UDP check depends on icmp reply(port/host unreachable).
So please make sure icmp can work between nginx and backend server otherwise it will assume backend is alive if no any icmp reply.
