ioat: convert ioat_probe to pcim/devm
The driver currently duplicates much of what these routines offer, so
just use the common code. For example ->irq_mode tracks what interrupt
mode was initialized, which duplicates the ->msix_enabled and
->msi_enabled handling in pcim_release.
This also adds a check to the return value of dma_async_device_register,
which can fail.
