[ Upstream commit cbcc607e18422555db569b593608aec26111cb0b ]
The __send_and_alloc_skb() receives a skb ptr as a parameter but in case it fails the skb is not valid: - Send failed and released the skb internally. - Allocation failed.
The current code tries to release the skb in case of failure which causes redundant freeing.
