[GLib] Avoid accessing NetworkMDNSRegister after Avahi proxy creation is
cancelled
https://bugs.webkit.org/show_bug.cgi?id=308222
Reviewed by Philippe Normand.
When the NetworkMDNSRegister destructor runs, it calls
g_cancellable_cancel, which will cancel any ongoing asynchronos calls
where m_cancellable participates.
Calls in NetworkMDNSRegister::registerMDNSName are safe, as they only
access memory they've allocated, but g_dbus_proxy_new_for_bus in the
constructor keeps a pointer to "this" that would have been invalid after
the destructor has completed.
This reorders the callback so that the instance is only accessed when no
errors are reported.
