ath9k: fix beacon slot processing in ad-hoc mode
The recent cleanups in the beacon code fixed SWBA backoff calculation, however it did not remove a line of code that worked around the issues from the earlier version of the code. After the cleanup, the initial TSF based slot calculation now always returns 0 instead of ATH_BCBUF-1, so the previous hack that reversed the slot order needs to be removed, as ad-hoc mode does not use staggered beacons.
