The outstanding r/w requests counter is not decremented
back if IB r/w request fails.
As the result, the rdma qpair stops pumping the requests
after the number of ibv_post_send failures reaches
the threshold for outstanding r/w requests for that qpair.
The patch decrements qpair's r/w counter back in case of
ibv_post_send returns an error.
