  Allow multiple mounts of zfs datasets

Bug description:
  Pull upstream fix
  mounts-of-zfs-datasets to allow multiple mounts

  An attempt to mount an already mounted zfs dataset should return a new
  mount referencing the existing super block, but instead it returns an
  error. Operations such as bind mounts and unsharing mount namespaces
  create new mounts for the sb, which can cause operations to fail which
  involve unmounting and remounting the dataset.  This fix from Seth
  addresses this issue
