net/bpf: Avoid unused "sin_addr_len" warning when CONFIG_CGROUP_BPF is not set
It was reported that there is a compiler warning on the unused variable
"sin_addr_len" in af_inet.c when CONFIG_CGROUP_BPF is not set.
This patch is to address it similar to the ipv6 counterpart
in inet6_getname(). It is to "return sin_addr_len;"
instead of "return sizeof(*sin);".
Fixes: fefba7d1ae19 ("bpf: Propagate modified uaddrlen from cgroup sockaddr programs")
