libubus: add null for ubus_context object in ubus_shutdown()
At the moment, we do our own null checks before calling ubus_free(). The likely-hood of 'ctx' being null (in ubus_free()) is low, but since free() handles null, might make sense for ubus_free() to do so as well. Signed-off-by: Alexandru Ardelean <ardeleanalex@gmail.com>
