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.
