Subject: macvtap: fix use after free for skb_array during release

We've clean skb_array in macvtap_put_queue() but still try to pop from
it during macvtap_sock_destruct(). Fix this use after free by moving
the skb array cleanup to macvtap_sock_destruct() instead.

Fixes: 362899b8725b ("macvtap: switch to use skb array")
