scsi: lpfc: Requeue SCSI I/O to upper layer when fw reports link down
During heavy I/O stress tests with 100+ vports and cable pulls, it may take
a while before the vport logs back into the fabric to resume I/O.
Currently, the driver immediately fails the I/O with DID_ERROR.
Change behavior to return DID_REQUEUE, and rely on SCSI layer's max retry
of 5 before erroring out the I/O.
