orinoco: allow driver to specify netdev_ops

Allow the main drivers to specify a custom version of the net_device_ops
structure. This is required by orinoco_usb to supply a separate transmit
function.

Export existing net_device_ops callbacks so that the drivers can reuse
some of the existing code.
