tap: double-free in error path in tap_open()
[ Upstream commit 78e0ea6791d7baafb8a0ca82b1bd0c7b3453c919 ]
Double free of skb_array in tap module is causing kernel panic. When
tap_set_queue() fails we free skb_array right away by calling
skb_array_cleanup(). However, later on skb_array_cleanup() is called
again by tap_sock_destruct through sock_put(). This patch fixes that
issue.
Fixes: 362899b8725b35e3 (macvtap: switch to use skb array)
