Public bug reported: When creating an instance, the memory quota is used to contain video ram.
For an instance resize, the difference between the old flavor and the new flavor will be check, and update the quota usage, but if the old flavor and the new flavor define a different video ram in extra_specs, it will cause the memory quota to be incorrect. If a flavor defines 512MB of RAM and 64MB of video RAM, creating an instance will take up 576MB of memory quota, when resize this instance to a flavor defined 1024MB of RAM but 0MB of video RAM, it will take up 1088MB of memory quota, not 1024MB, and this 64MB memory quota usage will never be released.
