Useless. * rdma_accept and rdma_get_cm_event() return -1. Useless. * qemu_rdma_poll() returns either -1 or an unspecified negative value. Useless. * qemu_rdma_block_for_wrid(), qemu_rdma_write_flush(), qemu_rdma_exchange_send(), qemu_rdma_exchange_recv(), qemu_rdma_write() return a negative value that may or may not be an errno value. While reporting human-readable errno information (which a number is not) can be useful, reporting an error code that may or may not be an errno value is useless. Drop these error codes from the error messages.
