Minor refactor of _setup_instance_group()

This patch is a minor refactoring of the _setup_instance_group()
method in the filter scheduler.  The majority of the method was inside
of a conditional.  This primarily reverses that and reduces the
nesting depth used.  There should be no functional changes at all in
this patch.
