cifs: translate network errors on send to -ECONNABORTED
When the network stack returns various errors, we today bubble up the error to the user (in case of soft mounts). This change translates all network errors except -EINTR and -EAGAIN to -ECONNABORTED. A similar approach is taken when we receive network errors when reading from the socket. The change also forces the cifsd thread to reconnect during it's next activity.
