[PATCH V2 06/16] i3c: mipi-i3c-hci: Call hci_dma_xfer_done() from dequeue path

hci_dma_dequeue_xfer() relies on state normally updated by the DMA
interrupt handler. Ensure that state is current by explicitly invoking
hci_dma_xfer_done() from the dequeue path.

This handles cases where the interrupt handler has not (yet) run.
