ath9k: do not track cycle counter updates in powersave mode

While the chip is in powersave mode, the cycle counter updates do not
contain useful values. While the chip is in full sleep, the rx_clear
signal stays high, indicating a busy medium.
To ensure sane values, update cycle counters before going into
powersave, and clear them right after switching back to awake.
