eventfs: Keep the directories from having the same inode number as files

Browse Source 
commit 8898e7f288c47d450a3cf1511c791a03550c0789 upstream.

The directories require unique inode numbers but all the eventfs files
have the same inode number. Prevent the directories from having the same
inode numbers as the files as that can confuse some tooling.
