Log:
  MFV r302650: 6940 Cannot unlink directories when over quota
  
  illumos/illumos-gate@99189164df06057fb968ca7be701bb1a0d5da8c9
  
https://github.com/illumos/illumos-gate/commit/99189164df06057fb968ca7be701bb1a0d5da8c9
  
  https://www.illumos.org/issues/6940
    Similar to #6334, but this time with empty directories:
    $ zfs create tank/quota
    $ zfs set quota=10M tank/quota
    $ zfs snapshot tank/quota@snap1
    $ zfs set mountpoint=/mnt/tank/quota tank/quota
    $ mkdir /mnt/tank/quota/dir # create an empty directory
    $ mkfile 11M /mnt/tank/quota/11M
    /mnt/tank/quota/11M: initialized 9830400 of 11534336 bytes: Disc quota 
exceeded
    $ rmdir /mnt/tank/quota/dir # now unlink the empty directory
    rmdir: directory "/mnt/tank/quota/dir": Disc quota exceeded
    From user perspective, I would expect that ZFS is always able to remove 
files
    and directories even when the quota is exceeded.
