Dandan Bi c32be82e99 MdeModulePkg/HiiDB: Remove configuration table when it's freed (CVE-2019-14586) ...

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1995

Fix the corner case issue that the original configuration runtime
memory is freed, but it is still exposed to the OS runtime.
So this patch is to remove the configuration table to avoid being
used in OS runtime when the configuration runtime memory is freed.
