There's no need to differentiate an INIT that ended early because of
RFKILL from one that succeded.  Additionally, if INIT fails later,
during calibration, due to RFKILL, we can just return success and
continue as if we were already in RFKILL to start with.

Remove this unnecessary differentiation and do some other small
clean-ups while at it.

The corunning block was supposed to help in coex scenarios.
It required the driver to configure the firmware based on
the coupling between the two antennas of the devices.
This was never in use and the configuration sent by the
driver has always been blank.
Remove all that code.
