devlink: Fix incorrect skb socket family dumping

[ Upstream commit 0006c6f1091bbeea88b8a88a6548b9fb2f803c74 ]

The devlink_fmsg_dump_skb function was incorrectly using the socket
type (sk->sk_type) instead of the socket family (sk->sk_family)
when filling the "family" field in the fast message dump.

This patch fixes this to properly display the socket family.
