[SCSI] fc class: add fc host default default dev loss setting
This patch adds a fc_host setting to store the default dev_loss_tmo. It is used if the driver has a callack to get the value from the LLD. If the callback is not set, then we use the fc class module default value. Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
