This fixes an issue caused by Stefano's commit c58ef05e, "MatInode: set it to
false when using device matrices", which introduced flipping the inode.use flag
inside MatBindToCPU_SeqAIJCUSPARSE() and MatBindToCPU_SeqAIJViennaCL(). I have
found cases in which this would cause "Corrupted Petsc object, Missing Inode
Structure" errors. Only flipping inode.use to true if inode.size is nonzero
eliminates these errors.
