thin: fix pool_has_message return for NULL params

Browse Source 
When pool_has_message() is queried with NULL lv and 0 device_id
it should just return 'true' when there is any message queued.
So it needs to return negative value dm_list_empty().

Since there is no user for this code path in code currently,
this bug has not been triggered.
