ath9k: Don't reset TSF after scanning automatically

Reset automatically the TSF on re-enabling beaconing after scanning in = IBSS mode causes several problems. For example a new created IBSS netwo= rk can't age before an other node has joined, because scans are done au= tomatically in that case. And several other strange bugs more...

The TSF reset is done manually in the higher level mac80211 code in the=
cases were it's needed, so we don't need to do it here.
