Sylvain Rochet 4af297fc20 PPP: fix don't print valid LCP echo request/reply packets if the link is up
The check for link up was missing, meaning valid LCP echo request/reply
packets are filtered whatever the PPP state is, despite what the comment
says.

Fix it by checking the PPP state as we would like to have done when it
was written.
