disp: msm: sde: check all dirty properties during plane update

Previously when updating a plane's dirty features, if the
dirty all flag was set, the optimization was to break early.
This optimization left out color property updates for that plane.
This fix removes the mutex locks in the msm_prop function so
the break optimization is no longer needed. Function callers will
now need to acquire the lock and unlock the property lock when done.
Now the plane will iterate through all dirty properties.
