[FLINK-1533] [runtime] Fixes NPE in the scheduler
Adds checks to the method ```Scheduler.getFreeSubSlotForTask``` to handle
failed shared slot allocations. Before the slot was given to the
```SlotSharingGroupAssignment``` without checking that it is not null.
Consequently, a NullPointerException could occur in the
```SlotSharingGroupAssignment```.
