drbd: A fixes to the new resync speed code
* Mention P_DELAY_PROBE in the packet naming array * Do not corrupt the mdev->data.work list in case the timer goes off before delay_probe_work got handled by the worker * Do not mod_timer() twice for a single delay_probe pair Signed-off-by: Philipp Reisner <philipp.reisner@linbit.com> Signed-off-by: Lars Ellenberg <lars.ellenberg@linbit.com>
