[SCSI] lpfc: do not reset dev_loss_tmo in slave callout
This fixes a bug where the driver was resetting the rport dev_loss_tmo when devices were added by adding support for the get_host_def_dev_loss_tmo callout. Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
