description:
Core: silenced getsockopt(TCP_FASTOPEN) messages on FreeBSD.

FreeBSD returns EINVAL when getsockopt(TCP_FASTOPEN) is called on a unix
domain socket, resulting in "getsockopt(TCP_FASTOPEN) ... failed" messages
during binary upgrade when unix domain listen sockets are present in
the configuration.  Added EINVAL to the list of ignored error codes.
