nfp: abm: track all offload-enabled qdiscs
Allocate an object corresponding to any offloaded qdisc we are
informed about by the kernel. Not only the qdiscs we have a
chance of offloading.
The count of created objects will be used to decide whether
the ethtool TC offload can be disabled, since otherwise we may
miss destroy commands.
