1. rbd: do not try to run resizefs on an encrypted BlockMode volume …

   When a volume has AccessType=Block and is encrypted with LUKS, a resize
   of the filesystem on the (decrypted) block-device is attempted. This
   should not be done, as the application that requested the Block volume
   is the only authoritive reader/writer of the data.
   
   In particular VirtualMachines that use RBD volumes as a disk, usually
   have a partition table on the disk, instead of only a single filesystem.
   The `resizefs` command will not be able to resize the filesystem on the
   block-device, as it is a partition table.
   
   When `resizefs` fails during NodeStageVolume, the volume is unstaged and
   an error is returned.
   
   Resizing an encrypted block-device requires `cryptsetup resize` so that
   the LUKS header on the RBD-image is updated with the correct size. But
   there is no need to call `resizefs` in this case.
