From: Martin Petermann <martin.petermann@de.ibm.com>

If an open port fsf request times out (in erp) the 
corresponding erp_action member of the fsf 
request need to set to NULL. If the port structure
will be removed later-on there will be still a 
reference in the fsf request to the non existing
erp_action otherwise.
