gfs2: Fix inode height consistency check
The maximum allowed height of an inode's metadata tree depends on the
filesystem block size; it is lower for bigger-block filesystems. When
reading in an inode, make sure that the height doesn't exceed the
maximum allowed height.
Arrays like sd_heightsize are sized to be big enough for any filesystem
block size; they will often be slightly bigger than what's needed for a
specific filesystem.
