[PATCH 0/2] MR10853: oleaut32: Zero ITypeInfo::AddressOfMember out-pointer on failure.

[Francis De Brabandere (＠francisdb)]

For a TKIND_DISPATCH typeinfo built via ICreateTypeLib2, AddressOfMember
has no DLL backing and returns TYPE_E_BADMODULEKIND. Native sets the
out-pointer to NULL on this path; Wine currently leaves it untouched.

Match native behavior: clear *ppv at entry so callers see NULL when
AddressOfMember returns an error path (e.g. TYPE_E_BADMODULEKIND for
typeinfos with no DLL backing).
