ice: avoid bonding causing auxiliary plug/unplug under RTNL lock
RDMA is not supported in ice on a PF that has been added to a bonded interface. To enforce this, when an interface enters a bond, we unplug the auxiliary device that supports RDMA functionality. This unplug currently happens in the context of handling the netdev bonding event. This event is sent to the ice driver under RTNL context. This is causing a deadlock where the RDMA driver is waiting for the RTNL lock to complete the removal. Defer the unplugging/re-plugging of the auxiliary device to the service task so that it is not performed under the RTNL lock context.
