pimd: Ensure cleanup of S,G on ifchannel failure to create

Browse Source 
There exists a path for ifchannel creation that if a S,G
fails to create and a corresponding *,G ifchannel is there,
the S,G will be deleted but we were leaving the S,G in the
*,G ifchannel sources list.  Remove from the list in this case
