|Message:||at86rf230: we may be in BUSY_RX after commanding RX_ON
Checking arrival in RX_ON races with incoming traffic. If frame
reception begins before we have a chance to see that we've arrived
in RX_ON, at86rf230_state complains about unexpectedly finding the
transceiver in BUSY_RX.
This isn't the prettiest solution (and it doesn't check if we're
in BUSY_RX before even commanding the change, although I think
this shouldn't happen), but it makes the problem go away.
