[ofa-general] [PATCH] perftest : Corrected ibv_poll_cq calls

[Nicolas Morey Chaisemartin]

Hi,

WHile reading the code to undertsand the perftests, I noticed that in 2 
of them, the loop on ibv_poll_cq only exists when the call read a CQE, 
but not in the case of an error (though the code looks for an error 
return value right after).
(My apologies if patch isn't at the right format...First time using git.)
