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

Patch series "mm/damon: code simplifications and cleanups".

This patchset contains some code simplifications and cleanups for DAMON.


This patch (of 4):

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