soc/intel/xeon_sp: Refactor IOAT compiler optimization outs

Browse Source 
IOAT logics are optimized out for non-IOAT platforms where
CONFIG(HAVE_IOAT_DOMAINS) as false.

This patch puts CONFIG(HAVE_IOAT_DOMAINS) check together ahead
of is_ioat_iio_stack_res() check in the corresponding if
statement to fulfill the optimization outs.
