ext4_utils: xattr_assert_sane false positives
xattr_free_space() does not match kernel, it subtracts
sizeof(__u32) as a buffer zone to permit IS_LAST_ENTRY
to function. As documented in .../linux/fs/ext4/xattr.c:
+------------------+
| header |
| entry 1 | |
| entry 2 | | growing downwards
| entry 3 | v
| four null bytes | <<<< HERE is why sizeof(__u32)
| . . . |
| value 1 | ^
| value 3 | | growing upwards
| value 2 | |
+------------------+
