[PATCH BlueZ 1/1] mesh: Fix checks when restoring internal model state

[Inga Stotland <inga.stotland@xxxxxxxxx>]

This fixes incorrect conditional checks in restore_model_state()
which could lead to dereferencing a NULL pointer.

Wrong: if (l_queue_isempty(mod->bindings) || !mod->cbs->bind) ...
Fixed: if (!l_queue_isempty(mod->bindings) && cbs->bind) ...
