msm: mdss: configure clk_lane_cnt variable for recovery failure

The clk_lane_cnt variable is not reset when frame transfer timeout
happens. Due to this, the clk_lane_cnt is only incremented and never
decremented during this race condition. Fix this by resetting the
clk_lane_cnt variable when recovery failure happens
