[PATCH 2/2] ext4: kill 2 useless magic numbers

[PATCH 2/2] ext4: kill 2 useless magic numbers

[Li Zefan]

dx_root_limit() will never return 20, and I can't figure out
what 20 stands for. This function has never changed since htree
directory indexing was merged.

Similar for dx_node_limit() and the magic 22.
