e411a3af11 avcodec/ivi: Fix segfault on allocation error 
If allocating the tiles array for indeo 4/5 fails, the context is in an
inconsistent state, because the counter for the number of tiles is > 0.
This will lead to a segfault when freeing the tiles' substructures.
Fix this by setting the number of tiles to zero if the allocation was
unsuccessful.
