Don't dereference "data" when we know for sure it's NULL.

Hrm but what data->interface would be is specified by the iface
parameter? Just spit that out instead?

This is only a symptom of the problem that kzalloc() failed, and when 
you are getting into such a situation here you have bigger problems - 
and these are not related to this driver.

Feel free to send a different patch, but IMHO "Insufficient memory" 
alone is enough information in this case.

As a side note, dev_err() should be used instead of printk here, and
possibly in other places. Darrick, could you please send a patch fixing
this?
