datapath: Fix tunnel reconfiguration that does not change key data.
		
Without this commit, a pair of commands like
    ovs-dpctl add-if br0 gre0,type=gre,remote_ip=192.168.5.2,csum=true
    ovs-dpctl set-if br0 gre0,csum=false
would result in a csum of "true" for gre0, that is, the second command
would silently have no effect.  This could also happen when the key data
(such as remote_ip) changed but the port hash just happened to have the
same value.

This also fixes a small kernel memory leak in this case.

An upcoming commit implements the "ovs-dpctl set-if" command mentioned
above.
