ovl: update of dentry revalidate flags after copy up
[ Upstream commit b07d5cc93e1b28df47a72c519d09d0a836043613 ]
After copy up, we may need to update d_flags if upper dentry is on a
remote fs and lower dentries are not.
Add helpers to allow incremental update of the revalidate flags.
Fixes: bccece1ead36 ("ovl: allow remote upper")
