[PATCH v3 net-next 2/5] geneve: Pass struct geneve_dev to geneve_create_sock().

[Kuniyuki Iwashima <kuniyu@google.com>]

This is a prep patch to make a subsequent patch clean.

We will need to access geneve_dev->cfg.info.key.u.{ipv4,ipv6}.src
in geneve_create_sock() later.

Let's pass down struct geneve_dev from geneve_sock_add() to
geneve_create_sock() instead of individual config fields.
