samples: ipc: openamp_rsc_table: conditional virtio ID sent on IPM device

Browse source 
Some IPM devices return an error if we request to transfer data.
Use IPM_MAX_DATA_SIZE to determine if the virtio ID can be transferred
through the IPM device.
Send data to IPM only if CONFIG_IPM_MAX_DATA_SIZE is not zero.
