Philippe Mathieu-Daudé 2261d3939f memory: Make 'info mtree' not display disabled regions by default 
We might have many disabled memory regions, making the 'info mtree'
output too verbose to be useful.
Remove the disabled regions in the default output, but allow the
monitor user to display them using the '-D' option.

Before:
