[PATCH] libata: fix ata_port_detach() for old EH ports
ata_prot_detach() did nothing for old EH ports and thus SCSI hosts
associated with those ports are left dangling after they are detached
leaving stale devices and causing oops eventually. Make
ata_port_detach() remove SCSI hosts for old EH ports.
