Jan Kara 3473fa1981 ext4: don't allow overlapping system zones 
[ Upstream commit bf9a379d0980e7413d94cb18dac73db2bfc5f470 ]

Currently, add_system_zone() just silently merges two added system zones
that overlap. However the overlap should not happen and it generally
suggests that some unrelated metadata overlap which indicates the fs is
corrupted. We should have caught such problems earlier (e.g. in
ext4_check_descriptors()) but add this check as another line of defense.
In later patch we also use this for stricter checking of journal inode
extent tree.
