[PATCH 2/2] ipv4: Initialize on-stack cork more efficiently.

[David Miller <davem@davemloft.net>]

ip_setup_cork() explicitly initializes every member of
inet_cork except flags, addr, and opt.  So we can simply
set those three members to zero instead of using a
memset() via an empty struct assignment.
