Fixes #63423
Follow-up to #94236

Quits the blitting method when a lightmap cannot fit into an atlas. This should never happen though, and is only done to prevent an infinite loop.

TODO:

  • Return a more descriptive error. The current one pops up a window informing the user about the atlas being too big, which is not the case here.

I can't reproduce the issue in #63423 MRP as of 97b8ad1, but this PR works fine on the MRP too. Either way, adding this safeguard makes sense.
