ocfs2: Fix system inodes cache overflow.
When we store system inodes cache in ocfs2_super,
we use a array for global system inodes. But unfortunately,
the range is calculated wrongly which makes it overflow and
pollute ocfs2_super->local_system_inodes.
This patch fix it by setting the range properly.
The corresponding bug is ossbug1303.
