[XLA:GPU] Fix for "Transform dimension propagation to the functional …

…paradigm

"

I think that now it's perhaps possible that FusionContext::GetPropagatedDimOrdersAndRequirementsIfProfitablyFusible succeeds, but context.CombineDimOrdersAndReqs fails because of a "splittable_dimension_major_part_size" requirement.

Also continue is the same as break in this specific context, so I changed it to break.
