This patch changes the bpf_sk_assign() to take ARG_PTR_TO_BTF_ID_SOCK_COMMON such that they will work with the pointer returned by the bpf_skc_to_*() helpers also. The bpf_sk_lookup_assign() is taking ARG_PTR_TO_SOCKET_"OR_NULL". Meaning it specifically takes a literal NULL. ARG_PTR_TO_BTF_ID_SOCK_COMMON does not allow a literal NULL, so another ARG type is required for this purpose and another follow-up patch can be used if there is such need.
