    [VFATFS] FATGetNextDirEntry(): Fix 1 MSVC 'warning C4267' (#6179)
    
    Fix `warning C4267: '=': conversion from 'size_t' to 'USHORT',
possible loss of data`
    by explicitly casting to USHORT.
    This is OK as the line immediately before NULL-terminates the buffer within boundary.
    
    Addendum to commit 096a69471 (r6279).
