Log:
  Remove bogus if_free (before ether_ifattach) when ntb_transport_probe fails
  
  if_free does a lot more than just free memory; it stops packet processing.
  
  This might fix panic on detach after r290684 when the transport is already in
  use, i.e. when the net_softc context is fully populated and "valid" due to
  use in another subsystem that's directly poking at ntb_hw0
