Jakob Unterwurzacher dd3b9910ee sftp: persist "ssh command exited" error ...

If our ssh process has died, not only the next, but all subsequent
calls to clientError() should indicate the error.

restic output when the ssh process is killed with "kill -9":

  Save(<data/afb68adbf9>) returned error, retrying after 253.661803ms: Write: failed to send packet header: write |1: file already closed
