[PATCH v2] ext4: fix macro definition error of EXT4_DIRENT_HASH and EXT4_DIRENT_MINOR_HASH

[carrion bent <carrionbent@linux.alibaba.com>]

    the macro parameter 'entry' of EXT4_DIRENT_HASH and
    EXT4_DIRENT_MINOR_HASH was not used, but rather the
    variable 'de' was directly used, which may be a local
    variable inside a function that calls the macros.
    Fortunately, all callers have passed in 'de' so far,
    so this bug didn't have an effect.
