Subject: [PATCH] s3:libsmb: return NT_STATUS_CONNECTION_INVALID if the fd is
 -1

This way we can destinguish between requests which failed
because the connection broke after they were triggered
and the requests which are started on an already broken
connection.

This also moves the check to cli_smb_req_iov_send()
where it really belongs.
