eventfs: Implement tracefs_inode_cache
Create a kmem cache of tracefs_inodes. To be more efficient, as there are
lots of tracefs inodes, create its own cache. This also allows to see how
many tracefs inodes have been created.
Add helper functions:
tracefs_alloc_inode()
tracefs_free_inode()
get_tracefs()
