The ioatdma needs to be queisced and block all additional op submission
during reboots. When NET_DMA was used, this caused issue as ops were still
being sent to ioatdma during reboots even though PCI BME has been turned
off. Even though NET_DMA has been deprecated, we need to prevent similar
situations. The shutdown handler should address that.

Simplifying the end return. This existed in the original code but was
flagged when refactoring of the code made it appear it's new.

Since we are a "single" device driver now we no longer require the function
pointers in ioatdma_device. Remove.
