ppp: don't set sk_state to PPPOX_ZOMBIE in pppoe_disc_rcv()
Since 287f3a943fef ("pppoe: Use workqueue to die properly when a PADT is received"), pppoe_disc_rcv() disconnects the socket by scheduling pppoe_unbind_sock_work(). This is enough to stop socket transmission and makes the PPPOX_ZOMBIE state uncessary. Signed-off-by: Guillaume Nault <g.nault@alphalink.fr> Signed-off-by: David S. Miller <davem@davemloft.net>
