MFC svn 267065 and 267187
make sure ifp->if_transmit returns 0 if a buffer is enqueued.
This should also be merged to stable/9.
After this fix, drivers still known to have this bug are igxbe/ixv
and i40e.
Drivers using if_transmit are correct, and so are most of the
other drivers that reassing if_transmit.
Among other things, this bug causes panics when using netmap emulation
on top of generic drivers.
