Cloth Asset - Crash when importing morph targets into clothing

The sim morph import has been broken after a change to make it work for cooked assets.

Ticking the Import Sim Morph Targets checkbox crashes as soon as a skeletal mesh with morph target is specified..

• Run QAGame.
• Right click in content browser and do Physics/Cloth Asset
• Right click in the Dataflow graph window and add a SkeletalMeshImport node.
• In the Node Details panel, select Owen as the Skeletal Mesh.
• Tick the Import Sim Morph Targets checkbox.
• Right Click to evaluate the node if nothing happens.

Observed result: Crash, ClothCollection->IsValid(EClothCollectionExtendedSchemas::CookedOnly | EClothCollectionExtendedSchemas::SimMorphTargets)
Expected result: No crash.
