Subject: [PATCH] accel/rocket: Check the correct DMA irq status to warn about

Right now, the code checks the DMA_READ_ERROR state 2 times, while
I guess it was supposed to warn about both read and write errors.

Change the 2nd check to look at the write-error flag.

Fixes: 0810d5ad88a1 ("accel/rocket: Add job submission IOCTL")
