xfs: pass btree cursors to refcount btree tracepoints

Prepare the rest of refcount btree tracepoints for use with realtime
reflink by making them take the btree cursor object as a parameter.
This will save us a lot of trouble later on.

Remove the xfs_refcount_recover_extent tracepoint since it's already
covered by other refcount tracepoints.
