xfs: add log item recovery tracing
Currently there is no tracing in log recovery, so it is difficult to
determine what is going on when something goes wrong.
Add tracing for log item recovery to provide visibility into the log
recovery process. The tracing added shows regions being extracted
from the log transactions and added to the transaction hash forming
recovery items, followed by the reordering, cancelling and finally
recovery of the items.
