media: ti: j721e-csi2rx: fix list_del corruption
If ti_csi2rx_start_dma() fails in ti_csi2rx_dma_callback(), the buffer is
marked done with VB2_BUF_STATE_ERROR but is not removed from the DMA queue.
This causes the same buffer to be retried in the next iteration, resulting
in a double list_del() and eventual list corruption.
Fix this by removing the buffer from the queue before calling
vb2_buffer_done() on error.
This resolves a crash due to list_del corruption:
