[OE-core][whinlatter][PATCH v2 23/29] e2fsprogs: misc/create_inode.c: Fix for file larger than 2GB

[ankur.tyagi85@gmail.com]

From: Robert Yang <liezhi.yang@windriver.com>

Fixed:
$ dd if=/dev/zero of=../image.ext4 bs=1M count=4k
$ dd if=/dev/random of=../rootfs/largefile bs=1M count=3k
$ ./misc/mke2fs -t ext4 -d ../rootfs/ ../image.ext4
__populate_fs: Ext2 file too big while writing file "largefile"
mke2fs: Ext2 file too big while populating file system

This was because the offset is overflow, use __u64 to fix the problem.

Another code which uses ext2_off_t is copy_fs_verity_data(), but it only copies
the metadata, so it should be enough large for it, just leave it there.
