Call optimize bandwidth again.

I pinned the issue down to the four lines, which call optimize_bandwidth.
Unfortunately the commit message indicates, that its removal fixed other
issues, so it can not be simply put back in.

Maybe this one is also vendor specific voltage lowering. Are there some sys
nodes, which expose vendor adaptations? I’ve got one from MSI [1] with 130 Watt
TDP.
