    exfat: Set the unused characters of FileName field to the value 0000h
    
    [ Upstream commit 4ba6ccd695f5ed3ae851e59b443b757bbe4557fe ]
    
    Some fsck tool complain that padding part of the FileName field
    is not set to the value 0000h. So let's maintain filesystem cleaner,
    as exfat's spec. recommendation.
