Fix a crash when a hair system's `ParticleSettings` ID datablock was linked from another file but couldn't be found. This results in default settings, with `type = PART_EMITTER`, where the particle data still has a non-NULL `hair` pointer. Previously, copies of such a particle system would NOT copy hair data for non-hair particle systems, hence the pointer of the copy pointed to the original data, which got freed (at least) twice upon closing the blend file. This is now fixed by always copying the hair data, regardless of the particle system type. Reviewed by: mont29 Differential Revision: https://developer.blender.org/D13245
