The issue is that: We call cb_fn firstly, then add the related idxd_ops into the chan->ops_list. Then if in user's callback, we call spdk_idxd_submit_* function gain, then we will allocate new idxd_opts first. So if there is recursive spdk_idxd_submit_* in the call back function, then we will exhaust all the ops_pool resources. And the function will report -EBUSY issue in _idxd_prep_command function. And this patch fixes this issue by adding back idxd_ops before calling user's call_cb function.
