  lib-smtp: smtp-client-command - Avoid calling the callback for the DATA command during submission.

This causes a race condition in which the command object is already freed when
it is returned from smtp_client_command_data_submit(). This scenario occurs when
reading data for the first BDAT command fails.

  Log Message:
  -----------
  lib-smtp: smtp-client - Send correct size value for BDAT command when the data lacks CR.

The addition of CR was ignored in the size specification because the original
unaltered stream was used for the size calculations.
