Remove qp and mr support from qib and use rdmavt. These two changes

This seems to have removed support for mapping MRs in the QIB drivers,
as there doesn't seem to be any map_mr_sg method in either rdmavt
or qib in the current tree.
I think this is the stuff that didn't actually even work in qib and when I
moved stuff to rdmavt I just left it out. Actually I ported it then dropped
that patch:

Whilke we're at it: the mess in check_driver_override and check_support
will break the first time someone changes any method calls. Type safety
exists for a dricking reason - fix this mess to write a little more
code but be type savfe and don't rely on the ordering of fields or you
can keep the pieces as soon as this junk breaks. And it will break
soon!
We'll look into this. I'm certainly not opposed to adding more code and if
you have any ideas to improve it, feel free to throw them out.
