socket: do a generic_file_splice_read when proto_ops has no splice_read
splice(2) fails with -EINVAL when called reading on a socket with no splice_read set in its proto_ops (such as vsock sockets). Switch this to fallbacks to a generic_file_splice_read instead. Signed-off-by: Slavomir Kaslev <kaslevs@vmware.com> Signed-off-by: David S. Miller <davem@davemloft.net>
