ENOTCONN was returned when SMB2_ioctl(with_ipc=true) was called and no
ipc was available so I believe it is functionnaly equivalent
currently. Unless other NT_STATUS mapped to ENOTCONN can be returned in
that scenario but I don't think it can.

While rebasing this on top of Steve's for-next I've realized since IPC
is not part of the tcon list anymore it's not automatically
reconnected. I have to do more testing :(
