net: adjust socket level ICW to cope with ipv6 variant of {recv, send}msg
After the previous patch we have ipv{6,4} variants for {recv,send}msg, we should use the generic _INET ICW variant to call into the proper build-in. This also allows dropping the now unused and rather ugly _INET4 ICW macro v1 -> v2: - use ICW macro to declare inet6_{recv,send}msg - fix a couple of checkpatch offender in the code context Signed-off-by: Paolo Abeni <pabeni@redhat.com> Signed-off-by: David S.
