V4L/DVB (8898): pvrusb2: Be able to programmatically retrieve a control's default value
The pvrusb2 control mechanism up until now has used a constant int to hold a control's default value. This change makes it possible to retrieve the control's default through some other means, e.g. as a result of a query from lower level software.
