Fix crash going to edit mode of particles with copy on write

We can not rely on edit->psys, it is not set for particle edit,
and there is some logic deeper inside which does different things
dependent on that.

We need to replace those checks with some some HAIR vs. PARTICLES
flag and always set psys pointer.
