xfs option inode32 doesn't work and is ignored at the initial mount

Issue

• xfs option inode32 doesn't work and is ignored at the initial mount:

# mount -t xfs -o inode32 /dev/sdb1 /mnt
# mount | grep mnt
/dev/sdb1 on /mnt type xfs (rw,relatime,seclabel,attr2,inode64,noquota)

• Remounting with inode32 option works:

# mount -o remount,inode32 /mnt
# mount | grep mnt
/dev/sdb1 on /mnt type xfs (rw,relatime,seclabel,attr2,inode32,noquota)
