Bluetooth: Move EIR and CoD update functions to a better position
Due to the upcoming addition of a service cache timer the functions to update the EIR and CoD need to be higher up in mgmt.c in order to avoid unnecessary forward-declarations. This patch simply moves code around without any other changes in order to make subsequent patches more readable.
