msm: kgsl: Fix race condition in adreno_spin_idle() 



adreno_spin_idle spins for a timeout checking for gpu to idle.
Sometimes due to race conditions the timeout can occur before the
loop is executed. Change the logic to a do-while loop and add an
extra idle check after the timeout before returning failure.
