Removing the "fusb302" debugfs directory when unloading
the driver. That allows the driver to be loaded more then
ones.
This fixes an issue where the driver, if unloaded, can't be
re-loaded, as the "fusb302" debugfs directory already
exists. While here, removing useless condition when creating
the debugfs directory.
