Ryan Moeller 69534635ff MFOpenZFS: ZVOLs should not be allowed to have children ... zfs create, receive and rename can bypass this hierarchy rule. Update both userland and kernel module to prevent this issue and use pyzfs unit tests to exercise the ioctls directly. Note: this commit slightly changes zfs_ioc_create() ABI. This allow to differentiate a generic error (EINVAL) from the specific case where we tried to create a dataset below a ZVOL (ZFS_ERR_WRONG_PARENT).
