bridge: Fix double free and memory leak around br_allowed_ingress
br_allowed_ingress() has two problems.
1. If br_allowed_ingress() is called by br_handle_frame_finish() and
vlan_untag() in br_allowed_ingress() fails, skb will be freed by both
vlan_untag() and br_handle_frame_finish().
2. If br_allowed_ingress() is called by br_dev_xmit() and
br_allowed_ingress() fails, the skb will not be freed.
Fix these two problems by freeing the skb in br_allowed_ingress()
if it fails.
