static bool ipa_endpoint_skb_build(struct ipa_endpoint *endpoint,
In ipa_endpoint_skb_copy(), a new socket buffer structure is allocated so that some data can be copied into it. However, after doing this, if the endpoint has a null netdev pointer, we just drop free the socket buffer. Instead, check endpoint->netdev pointer first, and just return early if it's null. Also return early if the SKB allocation fails, to avoid the deeper indentation in the normal path.
