bpf, net: sock_map memory usage
sockmap and sockhash don't have something in common in allocation, so let's
introduce different helpers to calculate their memory usage.
The reuslt as follows,
- before
28: sockmap name count_map flags 0x0
key 4B value 4B max_entries 65536 memlock 524288B
29: sockhash name count_map flags 0x0
key 4B value 4B max_entries 65536 memlock 524288B
- after
28: sockmap name count_map flags 0x0
key 4B value 4B max_entries 65536 memlock 524608B
29: sockhash name count_map flags 0x0 <<<< no updated elements
key 4B value 4B max_entries 65536 memlock 1048896B
