This fixes bug #1042, which occured when an RX->OFF->RX sequence happened quickly enough that the loop in rx_mode() did not see the change. As a result, the enable_baseband_streaming() call at the start of that function was not repeated for the new RX operation, so RX progress stalled. To solve this, the vendor request handler now increments a sequence number when it changes the transceiver mode. Instead of the RX loop checking whether the transceiver mode is still RX, it now checks whether the current sequence number is the same as when it was started. If not, there must have been at least one mode change, so the loop exits, and the main loop starts the necessary loop for the new mode. The same behaviour is implemented for the TX and sweep loops. For this approach to be reliable, we must ensure that when deciding which mode and sequence number to use, we take both values from the same set_transceiver_mode request. To achieve this, we briefly disable the USB0 interrupt to stop the vendor request handler from running whilst reading the mode and sequence number together. Then the loop dispatch proceeds using those pre-read values.
