The CL includes below changes:
1. Change bool isAssociatedImageValid to void verifyAssociatedImageValid
since we always required that the validation check should never be false.
So ASSERT() is enough. Same to
Image11::isAssociatedStorageValid->Image11::verifyAssociatedStorageValid.
2. Remove the unnecessary if checking after ASSERT
3. Use override instead of virtual if the function is virtual and
is overriding a virtual function from the base class.
