Re: [PATCHv2] vsock: Fix blocking ops call in prepare_to_wait

We receoved a bug report from someone using vmware:

 ...

transport->stream_enqueue may call copy_to_user so it should
not be called inside a prepare_to_wait. Narrow the scope of
the prepare_to_wait to avoid the bad call. This also applies
to vsock_stream_recvmsg as well.
