CABQ calculation changes to try and fix some weird corner cases leading

to stuck beacons.

* Set the cabq readytime (ie, how long to burst for) to 50% of the total
  beacon interval time
* fix the cabq adjustment calculation based on how the beacon offset is
  calculated (the SWBA/DBA time offset.)

This is all still a bit magic voodoo but it does seem to have further
quietened issues with missed/stuck beacons under my local testing.
In any case, it better matches what the reference HAL implements.
