[PATCH 3/6] btrfs-progs: lowmem check: find dir_item by di_key in check_dir_item()

[damenly . su]

From: Su Yue <suy.f...@cn.fujitsu.com>

In check_dir_item, we are going to search corresponding
dir_item/index.

Commit 564901eac7a4 ("btrfs-progs: check: introduce
print_dir_item_err()") Changed argument name from key to di_key but
forgot to change the key name for dir_item search.
So @key shouldn't be used here. It should be @di_key.

Fixes: 564901eac7a4 ("btrfs-progs: check: introduce print_dir_item_err()")
