spapr/ddw: Reset DMA when the last non-default window is removed

Browse source 
PAPR+/LoPAPR says:
===
The platform must restore the default DMA window for the PE on a call
to the ibm,remove-pe-dma-window RTAS call when all of the following
are true:
 a. The call removes the last DMA window remaining for the PE.
 b. The DMA window being removed is not the default window

===

This resets DMA as PAPR mandates.
