mac80211: remove IBSS merge delay

This reverts 4a332a38
("mac80211: Give it some time to do the TSF sync").

There's no point in waiting with a new IBSS merge
just because the hardware hasn't merged up with
the old IBSS yet, and since 34e8f082 we no longer
attempt to merge with the IBSS we're already in.
