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
