dlm: change lock time stamping
Use ktime instead of jiffies for timestamping lkb's. Also stamp the time on every lkb whenever it's added to a resource queue, instead of just stamping locks subject to timeouts. This will allow us to use timestamps more widely for debugging all locks. Signed-off-by: David Teigland <teigland@redhat.com>
