vfs: fix race in rcu lookup of pruned dentry
Backport of commit 59430262401bec02d415179c43dbe5b8819c09ce
done by Hugh Dickins <hughd@google.com>
Don't update *inode in __follow_mount_rcu() until we'd verified that
there is mountpoint there. Kudos to Hugh Dickins for catching that
one in the first place and eventually figuring out the solution (and
catching a braino in the earlier version of patch).
