net: Preserve metadata on pskb_expand_head
pskb_expand_head() copies headroom, including skb metadata, into the newly
allocated head, but then clears the metadata. As a result, metadata is lost
when BPF helpers trigger an skb head reallocation.
Let the skb metadata remain in the newly created copy of head.
