Yuan Wang 8b764f460f vhost: fix guest to host physical address mapping 
Async copy fails when looking up hpa in the gpa to hpa mapping table.
This happens because the gpa is matched exactly in the merged
mapping table, and the merge loses the mapping entries.
A new range comparison method is introduced to solve this issue.

Fixes: 6563cf9238 ("vhost: fix async copy on multi-page buffers")
