Fixed in https://svn.open-mpi.org/trac/ompi/changeset/15850. I also
added much more descriptive error messages. FWIW: I've refrained
from adding text to the FAQ yet about the receive_queues MCA
parameter because we will likely be changing some of the parameters
due to changes in credit accounting in the not-distant future.

Thanks for pointing out the problem, Tim.

(Jeff kills all remaining MTTs still running from last night since
all the openib testing will fail...)
