The TSF has to be reset only once, upon bringing
the interface up in AP mode. For any beacon reconfigure calls
after that, resetting the TSF results in incorrect beacon generation.
The only exception is a change in the beacon interval,
which is indicated to the driver by mac80211 through
IEEE80211_CONF_CHANGE_BEACON_INTERVAL, handle this properly.

Software antenna tuning is broken because of an function
ordering problem during rt2x00link_tuner().

rt2x00link_precalculate_signal()
rt2x00leds_led_quality()
rt2x00lib_antenna_diversity()

rt2x00link_precalculate_signal() will reset the quality TX/RX counters,
however rt2x00lib_antenna_diversity() requires the RX counter to
see what RSSI value must be used for a particular antenna.
We can't change the ordering since rt2x00lib_antenna_diversity() might
reset other statistics which are needed by the function called earlier.

Move the reset of the quality TX/RX counters into a seperate function
and move the call to after rt2x00lib_antenna_diversity().
