[PATCH v2] fs/ntfs3: use kcalloc() instead of kzalloc()

[Lenko Donchev]

We are trying to get rid of all multiplications from allocation
functions to prevent integer overflows[1]. Here the multiplication is
obviously safe, but using kcalloc() is more appropriate and improves
readability. This patch has no effect on runtime behavior.
