RDMA/rtrs: fix uninitialized symbol 'cnt'
rtrs_clt_rdma_cq_direct returns an ninitialized value in cnt
if there is no session. This patch makes rtrs_clt_rdma_cq_direct
returns a negative value for block layer not to try again.
Fixes: 2958a995edc94 ("block/rnbd-clt: Support polling mode for IO latency optimization")
