[DLM] confirm master for recovered waiting requests

Fixing the following scenario:
- A request is on the waiters list waiting for a reply from a remote node.
- The request is the first one on the resource, so first_lkid is set.
- The remote node fails causing recovery.
- During recovery the requesting node becomes master.
- The request is now processed locally instead of being a remote operation.
- At this point we need to call confirm_master() on the resource since
  we're certain we're now the master node.  This will clear first_lkid.
- We weren't calling confirm_master(), so first_lkid was not being cleared
  causing subsequent requests on that resource to get stuck.
