Conrad Meyer ea9e23edf3 ioat(4): Read CHANSTS register for suspended/halted checks
The device doesn't accurately update the CHANCMP address with the device state
when the device is suspended or halted.  So, read the CHANSTS register to check
for those states.

We still need to read the CHANCMP address for the last completed descriptor.
