Unnecessary warning "LogChaosCloth: Warning: Invalid pattern data. Num pattern indices 0 != Num welded indices"... for all SKM cloth

This warning is technically correct, panel-based cloth is disabled, but it's expected and there's nothing the user can actually do about it.

This comes from a UDN.

Open any existing Skeletal Mesh with cloth data (NOT new Chaos Cloth Asset). 

The Log warning will appear

LogChaosCloth: Warning: Invalid pattern data. Num pattern indices 0 != Num welded indices 5952. Panel-based cloth is disabled for this LOD.

with the number 5952 being replaced with whatever number of indices on that particular cloth.
