Commit f1293b2f9bc3 split apart buffer block arrays but introduced
also the possibility of a recount of active
blocks (NumUniformBlocks/NumShaderStorageBlocks) which would be
incoherent with the actual amount of active
blocks (UniformBlocks/ShaderStorageBlocks) in the program.
This could cause a segmentation fault if trying to use the index of a
block in a link failed program.
