Replace "time_ms" with "time_10ms" in the file directory entry structure
and related functions.
The unit of create_time_ms/modify_time_ms in File Directory Entry are
not 'milli-second', but 'ceni-second'.
The reason for using 10ms instead of cs for the names is that the exfat
specification defines it as Create10msIncrement/LastModified10msIncrement.
