ceph: fix RCU case handling in ceph_d_revalidate()
For RCU case ->d_revalidate() is called with rcu_read_lock() and
without pinning the dentry passed to it. Which means that it
can't rely upon ->d_inode remaining stable; that's the reason
for d_inode_rcu(), actually.
Make sure we don't reload ->d_inode there.
