exfat: Fix bitwise operation having different size

Browse source

cpos has type loff_t (long long), while s_blocksize has type u32. The
inversion wil happen on u32, the coercion to s64 happens afterwards and
will do 0-left-paddding, resulting in the upper bits getting masked out.

Cast s_blocksize to loff_t before negating it.
