i3c: mipi-i3c-hci: Wait for NoOp commands to complete
When a transfer list is only partially completed due to an error,
hci_dma_dequeue_xfer() overwrites the remaining DMA ring entries with
NoOp commands and restarts the ring to flush them out.
While NoOp commands are expected to complete successfully, they may still
fail to complete if the DMA ring is stuck. Explicitly wait for the NoOp
commands to finish, and trigger controller recovery if they do not
complete or report an error.
This ensures that partially completed transfer lists are reliably
resolved and that a stuck ring is recovered promptly.
