Here is a patch that allows me to remove all the stub/ENOSYS methods

ibv_rc_pingpong and rping over mthca.
Steve, what's wrong with chelsio driver providing ENOSYS stubs?
All you are doing is making the code path longer for
drivers that do provide those entry points.

This patch is in response to a review comment from Roland. He didn't
want providers to have to stub these.
I'm not even sure this is possible, but could we create an rdma_nosys() routine
that takes a variable arguments and simply returns -ENOSYS, and set all
unimplemented functions to reference that routine? This could be done in the
core, and would avoid branches in the code paths.
