xfs: make the log ticket ID available outside the log infrastructure
The ticket ID is needed to uniquely identify transactions when doing busy extent matching. Delayed logging changes the lifecycle of busy extents with respect to the transaction structure lifecycle. Hence we can no longer use the transaction structure as a means of determining the owner of the busy extent as it may be freed and reused while the busy extent is still active. This commit provides the infrastructure to access the xlog_tid_t held in the ticket from a transaction handle. This avoids the need for callers to peek into the transaction and log structures to find this out.
