You have:

  -net nic,model=rtl8139  -net user
  -net user,smb=...

The -net thing comes in pairs (one is guest side, another is host side).
You have 3 of them, and the last one is not paired with the guest side.

I suspect this is your problem - qemu does not know how to handle the
unpaired -net user.

The whole -net syntax is obsolete - partly because of this common
misunderstanding and partly because whole architecture behind -net is
wrongly designed. You should use -netdev..-device instead of -net..-net.
(Unfortunately, many old guides in the internet still suggest to use
-net, but this is something we can't change in a moment).

Now, you use both -net user,smb=... which redirects ports used by
windows networking to custom samba instance with its own configuration,
with nothing shared from host samba. Yet you attach your smb.conf file.
Why?

I suggest you to use -netdev..-device syntax (which has, among other
things, detection of disconnected halves like you have now) as a start.
Personally I see no reason to try to debug issues coming from -net..-net.

Thanks,
