Subject: [PATCH] [SCSI] scsi_transport_fc: Protect against overflow in
 dev_loss_tmo

The rport structure defines dev_loss_tmo as u32, which is
later multiplied with HZ to get the actual timeout value.
This might overflow for large dev_loss_tmo values. So we
should be better using u64 as intermediate variables here
to protect against overflow.
