pc-bios/s390-ccw: Re-initialize receive queue index before each boot attempt
Now that we can boot from multiple boot devices, we have to make sure
to reinitialize static variables like rx_last_idx to avoid that they
contain garbage data during the second boot attempt (which can lead to
crashes when the code tries to access the wrong ring data).
