IB/qib: Remove qp and mr functionality from qib

Browse Source 
Remove qp and mr support from qib and use rdmavt. These two changes
cannot be reasonably be split apart into separate patches because they
depend on each other in mulitple places. This paves the way to remove
even more functions in subsequent patches.
