Don't attempt to lock the file descriptor in readv/writev if it's a socket

Summary:
There is no way to lock a socket on Windows, so these calls will always fail. Just don't do the lock on Windows.
To do it properly with sockets, this should probably be forwarding to `sendmsg`/`recvmsg`, but this is good enough for now.
