In case of socket disconnection during authorization phase (if user do 
not perform any action in authorization dialog), if g_slist_remove and 
cb_data_destroy are called here we will get a crash when auth_cb will be 
called with an error (as we will try to call both functions on already 
freed memory).
This is why I let auth_cb in charge of removing source from the list and 
freeing memory during authorization phase.
