[ Upstream commit 60e5ca8a64bad8f3e2e20a1e57846e497361c700 ]
Add missed bpf_map_charge_init() in sock_hash_alloc() and
correspondingly bpf_map_charge_finish() on ENOMEM.
It was found accidentally while working on unrelated selftest that
checks "map->memory.pages > 0" is true for all map types.
Before:
# bpftool m l
...
3692: sockhash name m_sockhash flags 0x0
key 4B value 4B max_entries 8 memlock 0B
After:
# bpftool m l
...
84: sockmap name m_sockmap flags 0x0
key 4B value 4B max_entries 8 memlock 4096B
Fixes: 604326b41a6f ("bpf, sockmap: convert to generic sk_msg interface")
