mac80211: mesh: decrease max drift
The old value was 30ms, which means mesh sync will treat any value below as merely TSF drift. This isn't really reasonable (typical drift is < 10us/s) since people probably want to adjust TSF in smaller increments (for ie. beacon collision avoidance) without mesh sync fighting back. Change max drift adjustment to 0.8ms, so manual TSF adjustments can be made in 1ms increments, with some margin.
