hwc: rgz: Fix invalid dirty region state when HDMI is connected
It is possible when the HDMI cable is plugged in a geometry change
doesn't happen, hence the layers handled by the DSS and the
regionizer differ, since the dirty region counters are only reset
when a geometry change happens, this causes them to enter into
an invalid state leading to visual artifacts.
This fix compares if at any given time, the layers handled in the
regionizer differ in number from the previous frame, if that happens,
the dirty region counters are reset for all the layers.
