[SCSI] qla2xxx: Disable port-type RSCN handling via driver state-machine.
Given the semantic changes in both the device-model and fc-transport APIs, the driver's handling of port-type RSCNs via a series of ADISCs and PLOGIs can cause series of badness ranging from unexpectedly device loss to devices not being discovered. In the interim, disable (via a module-parameter) this feature and allow RSCN management to continue to occur within the driver's DPC thread.
