datapath: Don't query time for every packet.
		
Rather than actually query the time every time a packet comes through,
just store the current jiffies and convert it to actual time when
requested.  GRE is the primary beneficiary of this because the traffic
travels through the datapath twice.  This change reduces CPU utilization
3-4% with GRE.
