net_sched: optimize tcf_match_indev()
tcf_match_indev() is called in fast path, it is not wise to search for a netdev by ifindex and then compare by its name, just compare the ifindex. Also, dev->name could be changed by user-space, therefore the match would be always fail, but dev->ifindex could be consistent. BTW, this will also save some bytes from the core struct of u32.
