mm/damon: simplify the parameter passing for 'check_accesses' 

Patch series "mm/damon: Simplify the damon regions access check", v2.

This patchset simplifies the operations when checking the damon regions
accesses.


This patch (of 2):

The parameter 'struct damon_ctx *ctx' isn't used in the functions
__damon_{p,v}a_check_access(), so we can remove it and simplify the
parameter passing.
