Compare UDP_COALESCED_INFO against cmsg_type not cmsg_level

[mxinden]

As far as I can tell, UDP_COALESCED_INFO is a cmsg_type, not cmsg_level. The corresponding cmsg_level should be IPPROTO_UDP.

picoquic/picoquic/picosocks.c

Line 400 in 6f1c5f4

else if (cmsg->cmsg_level == UDP_COALESCED_INFO) {

See msquic implementation for reference:

Hope I am not missing something.

@mxinden Thanks for finding that! The interesting part is that tests of the existing code were working, although maybe by chance. I have a fix in PR #1773, if you want to take a look.
