Crash when enabling r.PSOPrecache.Resources due to check() in FSkeletalMeshObjectGPUSkin::GetUsedVertexFactoryData

The game crashes because of a nullptr SkinnedMeshComponent in  FSkeletalMeshObjectGPUSkin::GetUsedVertexFactoryData when r.PSOPrecache.Resources is enabled and a skeletal mesh is loaded due to a new check() added to FSkeletalMeshObjectGPUSkin::GetUsedVertexFactoryData in CL 36036396.  USkinnedAsset::PostLoad() calls GetVertexFactoryTypesPerMaterialIndex() with a nullptr SkinnedMeshComponent . This crash didn't occur in 5.4.

1. Add r.PSOPrecache.Resources=1 in DefaultEngine.ini
2. Run the game
3. Load a level with skeletal meshes

Expected
Game doesn't crash

Actual
Game crashes at newly added check() in FSkeletalMeshObjectGPUSkin::GetUsedVertexFactoryData added in CL 36036396
