vfs_ceph_new: Do not resolve by inode number

vfs_ceph_new: Do not resolve by inode number

CephFS snapshots within snap directory shares the same inode number from
its parent. Until unless we resolve by name we may incorrectly point at
an inode which is not a snapshot directory. Therefore to be functionally
correct we avoid resolving by inode number but proper name.

For example:

path (ino = 3)
  |
  --- dir (ino = 4)
  |
  --- .snap (ino = 3)
        |
        --- snap1 (ino = 3)
              |
              --- dir (ino = 4)

In this case an attempt to resolve 'snap1' by inode number 3 results in
pointing at 'path' which is not the desired outcome.
