From: Kaixu Xia <kaixuxia@tencent.com>

In the beginning there is only one damos_action 'DAMOS_PAGEOUT'
that need to get the coldness score of a region for a scheme,
which using damon_pageout_score() to do that. But now there are
also other damos_action actions need the coldness score, so
rename it to damon_cold_score() to make more sense.
