tracefs: Rename and export some tracefs functions

Export a few tracefs functions that will be needed by the eventfs dynamic
file system. Rename them to start with "tracefs_" to keep with the name
space.

start_creating -> tracefs_start_creating
failed_creating -> tracefs_failed_creating
end_creating -> tracefs_end_creating
