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.
