Lv YunlongandGreg Kroah-Hartman d9670f5e77 drivers/net/wan/hdlc_fr: Fix a double free in pvc_xmit ...

[ Upstream commit 1b479fb801 ]

In pvc_xmit, if __skb_pad(skb, pad, false) failed, it will free
the skb in the first time and goto drop. But the same skb is freed
by kfree_skb(skb) in the second time in drop.

Maintaining the original function unchanged, my patch adds a new
label out to avoid the double free if __skb_pad() failed.
