  datapath: check for rx handler register

Red Hat Enterprise Linux 6 has backported the netdev RX
handler facility so use the netdev_rx_handler_register as
an indicator.

The handler prototype changed between 2.6.36 and 2.6.39
since there could be backports in any stage, don't look
at the kernel version, but at the prototype.
