Fix the problem that the data field of Entry in the verifyLogicalOrUltraHighResCameraMetadata function is empty

The reason for this problem is: local variables are used when saving
PhysicalCameraCharacteristics. When its life cycle ends, physChars will
be released. Since Entry uses a pointer, data will be null. So physChars
should be defined outside else to ensure that physChars is not released
during use
