[Mesa-dev] [PATCH 1/2] _meta_GenerateMipmap: Set MaxLevel before allocating level

The radeon driver will fail to allocate miptree space for a new level
that is outside of BaseLevel..MaxLevel. Then it fails later, trying to
migrate the level to a miptree. Set MaxLevel to dstLevel before
allocating the level, and avoid triggering the problem.
