bridge: netfilter: fix update_pmtu crash with GRE
As GRE tries to call the update_pmtu function on skb->dst and
bridge supplies an skb->dst that has a NULL ops field, all is
not well.
This patch fixes this by giving the bridge device an ops field
with an update_pmtu function. For the moment I've left all
other fields blank but we can fill them in later should the
need arise.
Based on report and patch by Philip Craig.
