opt_to_gvar: print an error message for unsupported data types

Unsupported data types are silently ignored in opt_to_gvar() switch
statement. This leads to confusion as sigrok-cli just exits without
giving the user any hint on what's the reason for not setting the option
properly.

Add an error message for unmatched data types.
