    tinyusb/msc_fat_view: Fix file extension for short names
    
    Short name generation incorrectly build file extension.
    For config.txt it would create
    
    'CONFIG  .TX' instead of 'CONFIG  TXT'
    (Extra dot that should not be there)
    
    Now short name is displayed correctly
    Additionally typo in variable name is corrected.
