If an erroneous CQE is polled in the first iteration (i.e. npolled == 0), we don't update the consumer index and hence the hardware could get a wrong notion of how many CQEs software polled. Fix this by unconditionally updating the doorbell record. We could change the check to be something like if (npolled || err != -EAGAIN) ... but it does not seem worth the effort since a posted write to memory should not cost too much.
