[SCSI] qla2xxx: defer topology discovery to DPC thread during initialization.
Modify intialization semantics:
- perform basic hardware configuration only (as usual)
- allocate resources
- load and execute firmware
- defer link (transport) negotiations to the DPC thread
- again the code in qla2x00_initialize_adapter() to stall probe()
completion was needed for legacy-style scanning.
- DPC thread stalls until probe() complete.
- before probe() completes, set DPC flags to perform loop-resync logic
(similar to what's done during cable-insertion/removal).
Benefits: user does not have to wait 20+ seconds in case the FC cable
is unplugged during driver load, code consolidation (removal of
redundant link negotiation logic during initialize_adaoter()), and
finilly, the driver no longer needs to defer the fc_remote_port_add()
calls to hold off lun-scanning prior to returning from the probe()
function.
