Fix T95871: Non-float textures report as float.

Althought the float buffers are only used as cache, current code paths
don't look at the flags to identify which kind of image it is. Actual
fix would be to check flags, but that wouldn't be something to add one
week before release.

This commit fixes it by removing the buffers after use in the image
engine.
