RDMA/uverbs: Don't set rcq for a QP if qp_type is IB_QPT_XRC_INI
An INI QP doesn't require receive CQ, the creation flow sets the recv counts to zero: if (cmd->qp_type == IB_QPT_XRC_INI) { cmd->max_recv_wr = 0; cmd->max_recv_sge = 0; The new IOCTL path also does not set the rcq, so make things the same.
