bpf, net: xskmap memory usage
A new helper is introduced to calculate xskmap memory usage.
The xfsmap memory usage can be dynamically changed when we add or remove
a xsk_map_node. Hence we need to track the count of xsk_map_node to get
its memory usage.
The result as follows,
- before
10: xskmap name count_map flags 0x0
key 4B value 4B max_entries 65536 memlock 524288B
- after
10: xskmap name count_map flags 0x0 <<< no elements case
key 4B value 4B max_entries 65536 memlock 524608B
