2012-02-29[SCSI] isci: kill iphy->isci_port lookupsDan Williams
This field is a holdover from the OS abstraction conversion. The stable phy to port lookups are done via iphy->ownining_port under scic_lock. After this conversion to use port->lldd_port the only volatile lookup is the initial lookup in isci_port_formed(). After that point any lookup via a successfully notified domain_device is guaranteed to be valid until the domain_device is destroyed. Delete ->start_complete as it is only set once and is set as a consequence of the port going link up, by definition of getting a port formed event the port is "ready". While we are correcting port lookups also move the asd_sas_port table out from under the isci_port. This is to preclude any temptation to use container_of() to convert an asd_sas_port to an isci_port, the association is dynamic and under libsas control.
