Subject: samples/damon: change enable parameters to enabled
Date: Mon, 7 Jul 2025 11:45:47 +0900

The damon_{lru_sort,reclaim,stat} kernel modules use "enabled" parameter
knobs as follows.

  /sys/module/damon_lru_sort/parameters/enabled
  /sys/module/damon_reclaim/parameters/enabled
  /sys/module/damon_stat/parameters/enabled

However, other sample modules of damon use "enable" parameter knobs so
it'd be better to rename them from "enable" to "enabled" to keep the
consistency with other damon modules.

Before:
  /sys/module/damon_sample_wsse/parameters/enable
  /sys/module/damon_sample_prcl/parameters/enable
  /sys/module/damon_sample_mtier/parameters/enable

After:
  /sys/module/damon_sample_wsse/parameters/enabled
  /sys/module/damon_sample_prcl/parameters/enabled
  /sys/module/damon_sample_mtier/parameters/enabled

There is no functional changes in this patch.
