[PATCH v3 xfstests 1/2] generic/002: simplify the hardlink count test

[ChenXiaoSong <chenxiaosong@chenxiaosong.com>]

From: ChenXiaoSong <chenxiaosong@kylinos.cn>

Add the test to the hardlink group and replace the enumerated link
counts with arithmetic loops.

Clean up the test header, use "Silence is golden" success message,
and return the test status explicitly.

Suggested-by: Zorro Lang <zlang@kernel.org>
