mm/damon/lru_sort: use 'struct damon_attrs' for storing parameters for it

mainline inclusion
from mainline-v6.2-rc6
commit 135e128f
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I6MRUG

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=135e128f8e48f30ea65e0ffad34dca37d2c8d171

--------------------------------

DAMON_LRU_SORT receives monitoring attributes by parameters one by one to
separate variables, and then combines those into 'struct damon_attrs'.
This commit makes the module directly stores the parameter values to a
static 'struct damon_attrs' variable and use it to simplify the code.
