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.

I'm not sure I understand what's going on here. The dstLevel should
already be <= the texture max level. See the loop at line 2376. If
you step into the new _mesa_TexParameteri() call with gdb, are you
seeing dstLevel > texObj->MaxLevel?
