Camera: Compare old and new overrides for finishConfigure

With the new dataSpace/format override logic, during
finishConfiguration, we shouldn't check mDataSpaceOverride flag anymore
because now mDataSpaceOverride will be true for reconfigure.

Instead, we should check if the new override is the same as old
override.

Test: testPrepare on HAL device with dataSpace override
