net: remove duplicate code.
netdev_rx_handler_register() checks to see if the handler is already busy which was recently separated into netdev_is_rx_handler_busy(). So use the same function inside register() to avoid code duplication. Essentially this change should be a no-op Signed-off-by: Mahesh Bandewar <maheshb@google.com> Signed-off-by: David S.
