thin: send messages to active pool

Browse Source 
If the thin pool is known to be active, messages can be passed
to the pool even when the created thin volume is not going to be
activated.

So we do not need to stack large list of message and validate
and catch creation errors earlier in this case.

Replace the test for valid activation combination with simpler list of
deactivation combinations.
