[OpenJDK 2D-Dev] RFR: 8263981: java.awt.image.ComponentSampleModel equals/hashcode use numBands twice

[Aleksey Shipilev]

SonarCloud reports the problem in ComponentSampleModel.equals:
  Correct one of the identical sub-expressions on both sides of operator "&&"

...near "this.numBands == that.numBands". It is checked twice. hashCode also processes it twice.
