dbcc checkalloc errors after upgrade

[CR #271948] After you upgrade databases, dbcc checkalloc may display the following error message for various system tables:

Table with object id= n(name = name) is inconsistent
after Large Scale Allocation. Page n in extent n is
found reserved.

Workaround: This message is caused by consistency checks in the latest version of dbcc. It does not represent a problem with named objects. To avoid these messages, run dbcc checkalloc with the fix option after upgrading to Adaptive Server.
