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

Browse Source 
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.
