[serial/VirtualSerial2] code is not concise enough

    symbolicLinkName.Length = (USHORT)((wcslen(comPort.Buffer) * sizeof(wchar_t))

replace it with the following code：

status = RtlUnicodeStringCopyString(&symbolicLinkName, SYMBOLIC_LINK_NAME_PREFIX);
if (!NT_SUCCESS(status)) 
{
    Trace(TRACE_LEVEL_ERROR,
        "Error: Cannot create symbolic link name");
    goto Exit;
}
status = RtlUnicodeStringCat(&symbolicLinkName, &comPort);
if (!NT_SUCCESS(status)) {
    Trace(TRACE_LEVEL_ERROR,
        "Error: Cannot create symbolic link name");
    goto Exit;
}
