plugins/admin: Fix heap-use-after-free when using 2 controllers This commit fixes the heap-use-after-free error when connecting 2 controllers. When a controller is connected admin_policy_adapter_probe is called. If policy_data was already allocated it gets freed, if not, it only gets allocated. Eventually add_interface is called. Here policy_data is put in the "data" variable (specific for each controller) and the process_changes task is called with idle priority. This function ultimately accesses policy_data from the "data" variable. When Bluez crashes the flow is: 1)first controller is attached 2)admin_policy_adapter_probe is called and policy_data is allocated 4)second controller is attached 5)admin_policy_adapter_probe is called and policy_data is freed, then allocated again 6)process_changes runs and the policy_data for the first controller is read, but it was already freed, thus the crash
