memory-mapping: skip non-volatile memory regions in GuestPhysBlockList 

GuestPhysBlockList is currently used to produce dumps. Given the size
and the typical usage of NVDIMM for storage, they are not a good idea
to have in the dumps. We may want to have an extra dump option to
include them. For now, skip non-volatile regions.

The TCG memory clear function is going to use the GuestPhysBlockList
as well, and will thus skip NVDIMM for similar reasons.
