idr: introduce idr_for_each_entry_continue_ul()
Similarly, other callers of idr_get_next_ul() suffer the same
overflow bug as they don't handle it properly either.
Introduce idr_for_each_entry_continue_ul() to help these callers
iterate from a given ID.
cls_flower needs more care here because it still has overflow when
does arg->cookie++, we have to fold its nested loops into one
and remove the arg->cookie++.
Fixes: 01683a146999 ("net: sched: refactor flower walk to iterate over idr")
Fixes: 12d6066c3b29 ("net/mlx5: Add flow counters idr")
