Subject: [PATCH] tracefs: Remove kerneldoc from struct eventfs_file

The struct eventfs_file is a local structure and should not be parsed by
kernel doc. It also does not fully follow the kerneldoc format and is
causing kerneldoc to spit out errors. Replace the /** to /* so that
kerneldoc no longer processes this structure.

Also format the comments of the delete union of the structure to be a bit
better.
