Previously, ENABLE command ended up freeing the hostapd_iface context on initialization failures, but did not even remove the interface from the list of available interfaces. This resulted in use of freed memory with any following operation on the same interface. In addition, removing the interface on initialization failure does not seem like the best approach. Fix both of these issues by leaving the interface instance in memory, but in disabled state so that the configuration can be fixed and ENABLE used again to enable the interface or REMOVE used to remove the interface.
