Vasiliy Kovalev 7746b46e96 ovl: Filter invalid inodes with missing lookup function 
commit c8b359dddb418c60df1a69beea01d1b3322bfe83 upstream.

Add a check to the ovl_dentry_weird() function to prevent the
processing of directory inodes that lack the lookup function.
This is important because such inodes can cause errors in overlayfs
when passed to the lowerstack.
