f2fs: fix to avoid overflow when left shifting page offset
We use following method to calculate size with current page index:
size = index << PAGE_SHIFT
If type of index has only 32-bits size, left shifting will incur overflow,
which makes result incorrect.
So let's cast index with 64-bits type to avoid such issue.
