Use stderr for 'no pools/datasets available' error

Browse Source 
The 'zfs list' and 'zpool list' commands output the message
'no datasets/pools available' to stdout.  This should go to
stderr and only the available datasets/pools should go to
stdout.  Returning nothing to stdout is expected behavior
when there is nothing to list.
