[PATCH] Bluetooth: Fix not clearing ack timer when sending an i-frame

[Luiz Augusto von Dentz <luiz.dentz@gmail.com>]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

When sending an i-frame the first time unacked_frames is incremented
which means we are waiting an ack and there is no need to send an ack
since the i-frame itself already serve that purpose.
