'set' parameter does not need be passed by reference, pass by value is enough.

The validations look somewhat inconsistent in service_update function, we are
validating some parameters and not some.
Suggest bringing the validation of the service id also into this function and
remove it from the calling functions.

We do not need the above line. 'enabled' can be passed directly to
'service_update'.
