exfat: reuse __exfat_write_inode() to update directory entry
__exfat_write_inode() is used to update file and stream directory
entries, except for file->start_clu and stream->flags.
This commit moves update file->start_clu and stream->flags to
__exfat_write_inode() and reuse __exfat_write_inode() to update
directory entries.
