sysfs-tagging.txt: fix pre-kernfs references 

- sysfs_dirent is now kernfs_node - see commit 324a56e16e ("kernfs:
   s/sysfs_dirent/kernfs_node/ and rename its friends accordingly")

 - sysfs_super_info is now kernfs_super_info - see commit c525aaddc3
   ("kernfs: s/sysfs/kernfs/ in various data structures")

 - the 's_' prefix was dropped from various fields - see
   commit adc5e8b58f ("kernfs: drop s_ prefix from kernfs_node members")
