From: Mike Christie <michaelc@xxxxxxxxxxx>
This removes the driver's get_host_def_dev_loss_tmo
callback and just has the driver set the dev loss
using the fc class fc_host_dev_loss_tmo macro like is
done for other fc params.
It also adds compat support for the driver's existing
dev loss and nodev sysfs and modparams.
