Add kref_read() of mmu_rb_node.refcount in hfi1_mmu_rb_template-type tracepoint output. Change hfi1_mmu_rb_template tracepoint to take a struct mmu_rb_node* and record the values it needs from that. This makes the trace_hfi1_mmu*() calls shorter and easier to read. Add hfi1_mmu_release_node() tracepoint before all mmu_rb_node->handler->ops->remove() calls. Make hfi1_mmu_rb_search() tracepoint its own tracepoint type separate from hfi1_mmu_rb_template since hfi1_mmu_rb_search() does not take a struct mmu_rb_node*.
