xfs: create specialized classes for refcount tracepoints

Source kernel commit: bb0efb0d0a2885b4c65ca31e2815da2281b99153

The only user of the "ag" tracepoint event classes is the refcount
btree, so rename them to make that obvious and make them take the btree
cursor to simplify the arguments.  This will save us a lot of trouble
later on.
