bpf: lpm_trie memory usage
trie_mem_usage() is introduced to calculate the lpm_trie memory usage.
Some small memory allocations are ignored. The inner node is also
ignored.
The result as follows,
- before
10: lpm_trie flags 0x1
key 8B value 8B max_entries 65536 memlock 1048576B
- after
10: lpm_trie flags 0x1
key 8B value 8B max_entries 65536 memlock 2291536B
