[PATCH] bpf: declare bpf_sk_storage_get_cg_sock_proto

[PATCH] bpf: declare bpf_sk_storage_get_cg_sock_proto

[Ben Dooks]

The bpf_sk_storage_get_cg_sock_proto struct is exported from
net/core/bpf_sk_storage.c but is not decalred in any header
file. Fix the following sparse warning by adding it to the
include/net/bpf_sk_storage.h header:

net/core/bpf_sk_storage.c:334:29: warning: symbol 'bpf_sk_storage_get_cg_sock_proto' was not declared. Should it be static
