e2fsprogs: fix up check for hardlinks always false if inode > 0xFFFFFFFF
While file has a large inode number (> 0xFFFFFFFF), mkfs.ext4 could
not parse hardlink correctly.
Prepare three hardlink files for mkfs.ext4
$ ls -il rootfs_ota/a rootfs_ota/boot/b rootfs_ota/boot/c
11026675846 -rw-r--r-- 3 hjia users 0 Jul 20 17:44 rootfs_ota/a
11026675846 -rw-r--r-- 3 hjia users 0 Jul 20 17:44 rootfs_ota/boot/b
11026675846 -rw-r--r-- 3 hjia users 0 Jul 20 17:44 rootfs_ota/boot/c
$ truncate -s 1M rootfs_ota.ext4
$ mkfs.ext4 -F -i 8192 rootfs_ota.ext4 -L otaroot -U
fd5f8768-c779-4dc9-adde-
165a3d863349 -d rootfs_ota
$ mkdir mnt && sudo mount rootfs_ota.ext4 mnt
$ ls -il mnt/rootfs_ota/a mnt/rootfs_ota/boot/b
12 -rw-r--r-- 1 hjia users 0 Jul 20 17:44 mnt/a
14 -rw-r--r-- 1 hjia users 0 Jul 20 17:44 mnt/boot/b
15 -rw-r--r-- 1 hjia users 0 Jul 20 17:44 mnt/boot/c
After applying this fix
$ ls -il mnt/rootfs_ota/a mnt/rootfs_ota/boot/b
12 -rw-r--r-- 3 hjia users 0 Jul 20 17:44 mnt/a
12 -rw-r--r-- 3 hjia users 0 Jul 20 17:44 mnt/boot/b
12 -rw-r--r-- 3 hjia users 0 Jul 20 17:44 mnt/boot/c
