vldb_check: warn about cross-linked mh entries
Warn if an mh extent entry is referenced by more than one server
number in the IpMappedAddr table.
The serveraddr table is used to determine which server numbers have
IP addresses. If, for some reason, multiple server numbers
reference the same mh entry, currently, the correct serveraddr value
is calculated only for the lowest server number in the set of server
numbers which reference the same mh entry. Handle this case, and
warn about the duplicated values in the IpMappedAddr table.
Warn about IpMappedAddr entries which reference non-existent mh
blocks.
