In the non-mergeable receive case, when copy_mbuf_to_desc() call fails the packet is skipped, the corresponding used element len field is set to vnet header size, and it continues with next packet/desc. It could be a problem because it does not know why it failed, and assume the desc buffer is large enough. In mergeable receive case, when copy_mbuf_to_desc_mergeable() fails, packets burst is simply stopped. This patch makes the non-mergeable error path to behave as the mergeable one, as it seems the safest way. Also, doing this way will simplify pending IOTLB miss requests handling.
