i3c: mipi-i3c-hci: Do not unmap region not mapped for transfer
Fix following warning (with CONFIG_DMA_API_DEBUG) which happens with a
transfer without a data buffer.
DMA-API: i3c mipi-i3c-hci.0: device driver tries to free DMA memory it has not allocated [device address=0x0000000000000000] [size=0 bytes]
For those transfers the hci_dma_queue_xfer() doesn't create a mapping and
the DMA address pointer xfer->data_dma is not set.
