[SCSI] qla2xxx: Remove unused port-type RSCN handling code.

Expandind on the previous commit:

	commit 79f89a42
	Author: andrew.vasquez@qlogic.com <andrew.vasquez@qlogic.com>
	Date:   Fri Jan 13 17:05:58 2006 -0800

	[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.
