It may be redundant.  But, I need to think more about whether it can be removed.  There may be a case (with QP redirection perhaps?) where we'd want to return the GRH buffer to the user, but mark that the data's invalid.

I will see if there's a way to have the MAD receive completion match closer with the normal receive completion case.  For example, ib_wc is the only structure that uses bit fields for flags.  Other structures in the API use an integer set using enum values.
