btrfs-progs: check: verify name in dir_item for original mode
In original mode, we don't check if the name in dir_item matches the
hash in key.offset.
In the following case, original mode will report nothing wrong while
lowmem mode will detect the name and hash mismatch.
------
item 72 key (79177 DIR_ITEM 54846528) itemoff 12380 itemsize 88
location key (4222342 INODE_ITEM 0) type FILE
transid 170929 data_len 0 name_len 14
name: deprecated.sxt
location key (13590433 INODE_ITEM 0) type FILE
transid 796448 data_len 0 name_len 14
name: deprecated.txt
------
In above case, hash of "deprecated.txt" matches with 54846528,
while hash of "deprecated.sxt" should be 2008317993.
