permissions: switch from explicitly passing queue controller to callbacks

permissions: switch from explicitly passing queue controller to callbacks

Explicitly passing a raw QueueController object is extremely bad design
as it leads to inflexibility plus questions about lifetimes and ownership
of the pointer.

Moreover, with the new multiple permissions work, queue controller is
disappearing so using a callback means its replacement can be dropped
in without any modifications to the delegates.
