Fix T64101: Crash entering edit mode with particle system
Explicitly disable particles in edit for now. Those were not rendered already, but were attempted to be converted to Cycles structures (if UVs were not needed for hair nothing was rendered, but if UVs are needed then crash happened). Would be nice to bring hair in edit mode back, but this is a bit more involved change, which will be done later.
