Modified files:
	mld6igmp      xrl_mld6igmp_node.cc 

Log message:
	* Change the action for processing COMMAND_FAILED XRL error
	  within method :mld6igmp_client_send_add_delete_membership_cb()
	  from XLOG_FATAL() to print an error and continue with the
	  processing.
	  This is to avoid the following race condition:
	  If the MFEA is shutdown before MLD/IGMP and PIM,
	  then we may have both MLD/IGMP and PIM shutting down at the same time.
	  During that shutdown period, if MLD/IGMP sends delete_membership
	  XRL to PIM, PIM may return COMMAND_FAILED if it is in process of
	  deregistering with MLD/IGMP.
	
	* Add a check to XrlMld6igmpNode::proto_send() whether the MFEA
	  is alive, and return immediately if it is dead.
	  This upfront check is an optimization so we can avoid an unnecessary
	  XRL, and we can print a better error message.
