ppp: remove pch->chan NULL checks from tx path

Browse source

Now that ppp_disconnect_channel() is called before pch->chan is set to
NULL, a channel from ppp->channels list on the transmit path is
guaranteed to have non-NULL pch->chan.

Remove the pch->chan NULL checks from ppp_push(), ppp_mp_explode(), and
ppp_fill_forward_path(), where a channel is obtained from the list.
Remove the corresponding WRITE/READ_ONCE annotations as they no longer
race.
