A dump may be\nsplit across multiple skbs and remain pending after the initial request.\n\nNetlink pins the module which owns the dump callback, but in this case\nthat is the controller's owner rather than the target family's owner.  The\ntarget family can consequently be unregistered and its module unloaded\nwhile a policy dump is pending.  Advancing the dump then dereferences\npolicy memory from the unloaded module.\n\nTake a reference to the target family's module when the dump starts.\nDrop it from the error and done paths.  This matches the lifetime for which\nthe dump context retains the family and policy pointers."
