Subject: [PATCH] librbd: use new aio_create_completion()

to silence warnings like:

src/librbd/Utils.h:139:48: warning: 'static librados::v14_2_0::AioCompletion* librados::v14_2_0::Rados::aio_create_completion(void*, librados::callback_t, librados::callback_t)' is deprecated
[-Wdeprecated-declarations]
   return librados::Rados::aio_create_completion(
          ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^
     obj, &detail::rados_callback<T, MF>, nullptr);
     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
