In commit 27ecc6ba ("ntdll: Fix iosb handling in NtCancelIoFile()"),
NtCancelIoFile(Ex) was updated to return its status rather than
unconditionally setting it in io_status->u.Status (though the write
was retained in the success case). As a result, in the error case,
the kernelbase wrappers now interpret unitialized memory as an error
code, since io_status->u.Status is never written.
