commit 79f89a4296ff22f09baf538d4ff2a6d0c3097a73
Author: andrew.vasquez@qlogic.com <andrew.vasquez@qlogic.com>

[SCSI] qla2xxx: Disable port-type RSCN handling via driver state-machine.

and given:

- the process-context requirements of the FC transport
  rport-APIs.
- lack of port-type RSCN processing logic for ISP24xx and newer
  chips.

it's time now to remove the state-machine logic from mainline.
