EEVEE: Fix Lights On High-res Monitors

When using EEVEE on high resolution monitors the light buffers might not
get initialized as there are range checks that pass in the first try.

- number of tiles needed is larger than the max_tile_count_threshold
- total_word_count is smaller than max_word_count_threshold as it is
  never set (still initialized to zero.

Solution is to not exit on the first try. In a later stage we might want
to use something that doesn't require any looping.
