Cleanup: Various small issues noticed earlier

* Rename BKE_get_falloff_factor() to BKE_gpencil_multiframe_falloff_calc()
and make it return value instead of passing in a pointer to fill.

* Rename "gso->falloff" to "gso->mf_falloff" to be less ambiguous

* Fix indentation issues in gpencil_brush.c

Node selection: Stop operator when mouse selection selected a node
