Subject: [PATCH v3 net-next 08/15] socket: Pass hold_net to sk_alloc().
We will introduce a new API to create a kernel socket with netns refcnt
held. Then, sk_alloc() need the hold_net flag passed to __sock_create().
Let's pass it to sk_alloc().
The actual use of hold_net will be in the next patch to make its review
easy.
