Thin use origin_only for thin pools as well

Browse Source 
Extend the usage of origin_only flag to allow resume of thin pool LV
(when it's active) to pass only the messages.

origin_only flag will skip detection of already resumed tree for thin_pool,
so we do not need to suspend the tree and we just send messages.
