[patch] Fix crash when connection settings aren't set

[Sjoerd Simons <sjoerd luon net>]

Hi,

  If a service providing connections has aconnection without connection settings  NM crashes because the respective error doesn't get set. (And the error
  handling code assumes it is set)

  See attached patch

    Set the error if the settings don't contain a 'connection' substree. Prevents a crash in code assuming the error is set
