net_slirp_register_poll_sock() and net_slirp_unregister_poll_sock() report WSAEventSelect() failure with error_setg(&error_warn, ...).
I'm not familiar with liblirp, so I can't say whether the network backend will work after such a failure. If it doesn't, then this should be an error. If it does, then why bother the user with a warning that isn't actionable, and likely confusing? Regardless of that, error_setg_win32(&error_warn, ...) is undesirable just like error_setg(&error_fatal, ...) and error_setg(&error_abort, ...) are. Replace by warn_report().
