storage: Check if provided parent is vHBA capable
storage: Check if provided parent is vHBA capable

https://bugzilla.redhat.com/show_bug.cgi?id=1458708

If the parent provided for the storage pool adapter is not vHBA
capable, then issue a configuration error even though the provided
wwnn/wwpn were found.

It is a configuration error to provide a mismatched parent to
the wwnn/wwpn. The @parent is optional and is used as a means to
perform duplicate pool source checks.
