[PATCH 1/3] NTFS: aops: Remove VLA usage

In the quest to remove all stack VLA usage from the kernel[1], this uses the maximum size needed on the stack and adds a sanity check for robustness: index.block_size cannot be larger than PAGE_SIZE nor less than NTFS_BLOCK_SIZE. [1] https://lkml.kernel.org/r/CA+55aFzCG-zNmZwX4A2FQpadafLfEzK6CC=q
