mm/damon/core: use time_after_eq() in kdamond_fn()

Browse source

damon_ctx->passed_sample_intervals and damon_ctx->next_*_sis are unsigned
long.  Those are compared in kdamond_fn() using normal comparison
operators.  It is unsafe from overflow.  Use time_after_eq(), which is
safe from overflows when correctly used, instead.
