ioat: kill msix_single_vector support
Once we have determined that we will not have all of our desired msix
vectors there is no point in attempting a single msix allocation. The
driver will already need to read registers to determine the source of
the interrupt the fact that it is msix is moot. Fallback directly to
msi.
