Fix in logic to write EIR when SDP records are changed.
Fix in logic to write EIR when SDP records are changed.

Whenever SDP service record is added/deleted/modified check for whether
class of device needs to be updated as well. If the update is
needed, proceed as before: new EIR will be written subsequently.
If the class of device is already present, just update EIR and return.
