When we attempt to send a packet while the demultiplex thread is in the middle of cifs_reconnect() we may end up returning -ENOTSOCK to upper layers. The intent here is to retry the request once the TCP connection is up, so change it to return -EAGAIN instead. The latter error code is retryable and the upper layers will retry the request if needed.
