fix #H7352 - panic when floodfilling large areas

Special levels with FLAGS:inaccessibles could trigger a panic if a large enough area was subjected to floodfill handling. The buffer intended to be enough to hold an entire level wasn't big enough when individual coordinates were being added multiple times. I don't really understand what this code is doing but the recommended fix does work to prevent the panic. None of the levels included with 3.6.x were affected.
