clk: msm: clock-debug: acquire prepare lock during measurement
If the rate of the clock being measured changes at the same
time clock_debug_measure_get() is called, there can be a
miscalculation of the value of the divider between the
measurement circuitry and clock output. Acquiring the prepare
lock fixes the race since it prevents clock rate changes during
measurement.
