Hi,

When vmxnet3_rq_create() fails to allocate memory for rq->data_ring.base,
the subsequent call to vmxnet3_rq_destroy_all_rxdataring does not reset
rq->data_ring.desc_size for the data ring that failed, which presumably
causes the hypervisor to reference it on packet reception.

To fix this bug, rq->data_ring.desc_size needs to be set to 0 to tell
the hypervisor to disable this feature.
