Move SafeSymCleanup() call to cbExitProcess so it isn't called when the process may have already terminated

debugLoopFunction: set fdProcessInfo->hProcess and fdProcessInfo->hThread to NULL as these shouldn't be used after this point. The actual CloseHandle calls on these two handles are done by kernel32!ContinueDebugEvent immediately after cbExitProcess
