ssm: Make possible to set data via function

Browse source 
Use the same approach of GTask, making possible to set the data from a
function. Givent the fact that a SSM has now a device parameter, it's
generally not needed to pass an extra data value.

In such case make it possible to set it and to define a destroy-notify
function to handle its destruction when freeing the SSM.
