In soreceive_dgram, when a 0-length buffer is passed into recv(2) and
no data is ready, return 0 rather than blocking or returning EAGAIN.
This is consistent with the behavior of soreceive_generic (soreceive)
in earlier versions of FreeBSD, and restores this behavior for UDP.

Discussed with:	jhb, sam
MFC after:	3 days
