openamp: don't need check status when get_tx_payload

The call of rproc_virtio_get_status will access the resource table, but the resource table only belongs to the shm of one of the CPUs, so after sleep, the other CPU cannot access it, so we don't need to check the status for rpmsg_virtio_get_tx_payload_buffer every times.
