Adds support for RTNH_F_DEAD and RTNH_F_LINKDOWN flags on mpls
routes due to link events. Also adds code to ignore dead
routes during route selection.

I agree with Robert's feedback that we probably should use
ACCESS_ONCE(), optionally with a local variable.

Please make this change and I'll apply this patch, thanks Roopa!

ack, will send v7. thanks for review all!.
