Eliminate redundant changes to hardware vsync state.
When transitioning between NORMAL and DOZE power modes
we were redundantly calling resyncHardwareVsync.
Similarly, when transitioning from DOZE_SUSPEND to OFF
we were redundantly calling disableHardwareVsync.
This change eliminates those redundant calls.
Fixes bug 62235417
