x86_64: fix e820_hole_size based on address ranges
e820_hole_size() now uses the newly extracted helper function,
e820_find_active_region(), to determine the size of usable RAM in a range of
PFN's.
This was previously broken because of two reasons:
- The start and end PFN's of each e820 entry were not properly rounded
prior to excluding those entries in the range, and
- Entries smaller than a page were not properly excluded from being
accumulated.
This resulted in emulated nodes being incorrectly mapped to ranges that
were completely reserved and not candidates for being registered as
active ranges.
