Hi folks,

I was adapting msquic library to work with iouring and found an issue
with recvmsg() where it ignores O_NONBLOCK flag set on the file
descriptor. If MSG_DONTWAIT is set in flags, it behaves as expected.
I've attached a simple test which currently just hangs on iouring's
recvmsg(). I'm guessing sendmsg() behaves the same way but I have no
idea how to fill the buffer to reliably test it.

Best,
Hrvoje
