Ritesh Harjani (IBM) 7acd1b315c ext4: Add a WARN_ON_ONCE for querying LAST_IN_LEAF instead ...

We added the documentation in ext4_map_blocks() for usage of
EXT4_GET_BLOCKS_QUERY_LAST_IN_LEAF flag. But It's better to add
a WARN_ON_ONCE in case if anyone tries using this flag with CREATE to
avoid a random issue later. Since depth can change with CREATE and it
needs to be re-calculated before using it in there.
