raw/ioat: fix missing close function

When rte_rawdev_pmd_release() is called, rte_rawdev_close() looks for a
dev_close function for the device causing a segmentation fault when no
close() function is implemented for a driver.

This patch resolves the issue by adding a stub function ioat_dev_close().
