[PATCH 3.2 097/115] pppoe: fix reference counting in PPPoE proxy

[Ben Hutchings]

3.2.80-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Guillaume Nault <g.na...@alphalink.fr>

[ Upstream commit 29e73269aa4d36f92b35610c25f8b01c789b0dc8 ]

Drop reference on the relay_po socket when __pppoe_xmit() succeeds.
This is already handled correctly in the error path.
