qed: Share additional information with qedf
Share several new tidbits with qedf:
- wwpn & wwnn
- Absolute pf-id [this one is actually meant for qedi as well]
- Number of available CQs
While we're at it, now that qedf will be aware of the available CQs
we can add some validation on the inputs it provides.
