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.
