filesystem: CardProfile: initialize empty sw table as empty dict

The table that holds the status word descriptions is initialized as an
empty list '[]'. This is not correct since the interpret_sw method
processes this data as dictionary, so lets initialize the sw member with
an empty dict '{}' when not status word description is given.
