We must return -1 instead of ENOENT if the special zvol threading
property set function can't locate the dataset (this would typically
happen with an encypted and unmounted zvol) so that the operation
gets inserted properly into the nvlist for operations to set. This
is because we want the property to be set once the zvol is
decrypted again.
