mm/damon/paddr: initialize 'folio' variables to NULL for clarity
In damon_pa_mark_accessed_or_deactivate(), damon_pa_pageout(),
damon_pa_migrate(), and damon_pa_stat(), the local variable 'folio' is
declared but not initialized.
Initialize 'folio' to NULL to improve code readability and
maintainability.
