net: fixes for skb_send_sock
A couple fixes to new skb_send_sock infrastructure. However, no users
currently exist for this code (adding user in next handful of patches)
so it should not be possible to trigger a panic with existing in-kernel
code.
Fixes: 306b13eb3cf9 ("proto_ops: Add locked held versions of sendmsg and sendpage")
