Don't use wrong weight when passivating group

When we're passivating a metaslab group we start by passivating the 
metaslabs that have been activated for each of the allocators.  To do 
that, we need to provide a weight. However, currently this erroneously 
always uses a segment-based weight, even if segment-based weighting is 
disabled.

Use the normal weight function, which will decide which type of weight 
to use.
