net/mlx5: separate aging counter pool range
net/mlx5: separate aging counter pool range

Currently, when allocate the counter or counter based age from group 0,
counter and age may share the same counter dcs ID range. Both age and
pure counter need to sync up with each other's container to check if
the ID range exists and update the min_dcs.

It comes two disadvantages:
1. If the ID range is shared, this counter range will be queried twice
   both from age and pure counter container in 1s.
2. The same range counter check between the two container makes the
   counter allocate sync min_dcs time to time with extra min_dcs
   updating.

This patch avoid the same ID range to be shared when allocate the new
pool. If the same ID range exists in other container, just add the
counter to the other container until get new range which saves the
min_dcs sync up time to time.
