Show allocations increment/decrement logs behind verbose flag (#1677)

Fix #1657 

This log was added in a recent refactor for draining support and it is
very noisy. With this change the log is moved behind the "verbose" flag
and also does a minor cleanup to not have 2 duplicated lines for logging
when one is enough.
