Engine Crashes When Trying To Reimport Skeletal Mesh For One That Has No Clothing Data

The engine crashes when trying to reimport a skeletal mesh that has no clothing data.

This seems related to https://jira.it.epicgames.net/browse/UE-86948.

Found in 4.24.1 CL#10757647
Reproduced in 4.25 Main CL#109285306

1. Import a skeletal mesh that has a section that can be used for cloth simulation.
2. Make sure that it has clothing data applied.
3. Delete the the clothing data that is currently applied.
4. Try to Reimport the skeletal mesh.

Result: The engine crashes.

Expected: The skeletal mesh reimports without any issues.
