The results of non-blocking transmits were not correctly communicated
to userspace.

Specifically:

1) if a non-blocking transmit was canceled, then rx_status wasn't set to 0
   as it should.
2) if the non-blocking transmit succeeded, but the corresponding reply
   never arrived (aborted or timed out), then tx_status wasn't set to 0
   as it should, and rx_status was hardcoded to ABORTED instead of the
   actual reason, such as TIMEOUT. In addition, adap->ops->received() was
   never called, so drivers that want to do message processing themselves
   would not be informed of the failed reply.
