engines/rbd: fix compile without blkin support

If we don't have rbd-blkin support, compile fails with:

engines/rbd.c:21:26: error: field ‘info’ has incomplete type
  struct blkin_trace_info info;
                          ^~~~
Makefile:313: recipe for target 'engines/rbd.o' failed

Hide 'info' behind the ifdef.

Fixes: a4c4c3460bd5 ("Add support for blkin tracing in rbd engine")
