[PATCH 8/8] verbs: Remove tests for NULL ops

[Jason Gunthorpe <jgg-uk2M96/98Pc@public.gmane.org>]

From: Jason Gunthorpe <jgg-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

ops can no longer be null, the correct error return is generated inside
the dummy. This removes some overhead and fixes a missing errno = ENOSYS
in the create_srq path.

We cannot change the tests inlined the header file, since the app might link
to an older verbs.
