mm/damon: unified access_check function naming rules

Patch series "mm/damon: Do some small changes", v4.

This patch (of 4):

In damon/paddr.c file, two functions names start with underscore,
	static void __damon_pa_prepare_access_check(struct damon_ctx *ctx,
			struct damon_region *r)
	static void __damon_pa_prepare_access_check(struct damon_ctx *ctx,
			struct damon_region *r)
In damon/vaddr.c file, there are also two functions with the same function,
	static void damon_va_prepare_access_check(struct damon_ctx *ctx,
			struct mm_struct *mm, struct damon_region *r)
	static void damon_va_check_access(struct damon_ctx *ctx,
			struct mm_struct *mm, struct damon_region *r)

It makes sense to keep consistent, and it is not easy to be confused with
the function that call them.
