[SCSI] sd: Make revalidate less chatty
sd_revalidate ends up being called several times during device setup. With this patch we print everything during the first scan. Subsequent invocations will only print a message if the parameter in question has actually changed (LUN capacity has increased, etc.). Signed-off-by: Martin K.
