libdm: avoid checking status on activation

Browse Source 
Variable props.send_messages has 3 states and was not used properly
here.  Activation in this moment does not need to verify thin-pool status
as that has been already checked on preload.
So only if there are some real messages (value 2) call function
for sending them.
