This is really the tip of the iceberg here and this function's cleanup
really needs to be shored up more completely than this.

If the allocation of 'card' succeeds, and one of the "goto out_port"
paths are taken, 'card' is leaked because the last thing performed
is linking it into the list inside of 'priv'.

Anyways, I'll apply this but there are so many more leaks here.
