net: remove sk_init() helper

It seems sk_init() has no value today and even does strange things :

# grep . /proc/sys/net/core/?mem_*
/proc/sys/net/core/rmem_default:212992
/proc/sys/net/core/rmem_max:131071
/proc/sys/net/core/wmem_default:212992
/proc/sys/net/core/wmem_max:131071

We can remove it completely.
