        src/sys/dev/usb: if_axe.c if_smsc.c if_ure.c if_urndis.c usbnet.c

Log Message:
don't set dv_private.  it's a bad pattern and only didn't
trip kmem_free() lossage because struct usbnet is at the
start of the softc.

for now, enforce this as part of the ABI.

catch up urndis with tx_prepare checking buffer length,
and also add an assert to usbnet_start_locked() to match.
