cover IB/ehca: PMA support and a minor fix

This patchset will fix a minor issue and then add support for Performance MADs, which redirects all PMA queries to the actual PMA QP.

[1/2] adds a missing query_pma_attr()
[2/2] adds PMA redirection code

The patches will apply, in order, on top of Roland's for-2.6.25 branch. Please review them and apply for 2.6.25 if you think they're okay.

Thanks and regards,
Joachim
