Gracefully handle uv_read_start() failures

Gracefully handle uv_read_start() failures

Under specific rare timing circumstances the uv_read_start() could
fail with UV_EINVAL when the connection is reset between the connect (or
accept) and the uv_read_start() call on the nmworker loop.  Handle such
situation gracefully by propagating the errors from uv_read_start() into
upper layers, so the socket can be internally closed().
