rpmsg: let rpmsg_virtio_get_tx_buffer() always return idx in host side

In rpmsg host side, the tx buffer index is not assigned when this buffer is obtained from the reclaimer list, this commit let rpmsg_virtio_get_tx_buffer() always get correct idx. Note: the idx in rpmsg host side is not used, so this commit is just an improvement and not fix any issue. Signed-off-by: Guiding Li <[email protected]> Signed-off-by: Bowen Wang <[email protected]>
