Vladimir Kondratiev 19f0c83512 lib/sbi: optimize domain memory regions copying ...

There are 2 locations where memory regions moved in a bulk,
but this implemented in a region-by region move or even swap.

Use more effective way. Note, last entry, dom->regions[count], always
exists and is empty, copying it replaces clear_region()
