Fix T66812: Particles + Build Modifier = Crash 

Particles can not be used with a destructive modifiers, so we can not
maker such configuration fully reliable.

Not sure this specific setup ever worked in 2.7x, maybe DM index was
somehow reset somewhere in particle system in older Blender version,
or maybe all of Blender version were crashing.

Anyway, seems to be very easy to avoid obvious index past the array
boundary in the mapping,
