From: Sungjong Seo <sj1557.seo@xxxxxxxxxxx>
commit 0c336d6e33f4bedc443404c89f43c91c8bd9ee11 upstream.
When calculating i_blocks, there was a mistake that was masked with a
32-bit variable. So i_blocks for files larger than 4 GiB had incorrect
values. Mask with a 64-bit variable instead of 32-bit one.
Fixes: 5f2aa075070c ("exfat: add inode operations")
