habanalabs: order memory manager messages

Browse source 
Changing format of memory manager messages to make it more readable. In
addition, reducing the priority of a warning on missing handle during
put. This scenario is not an indication of a problem and may happen in
a legal flow, when handle is put from multiple flows. For example, in
timeout and completion.
