CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=d36d4a1d75d2a8bd14ec00d5cb0ce166f6886146

Intel-SIG: commit d36d4a1d platform/x86: ISST: Fix optimization with use of numa.
Backport for ISST driver fix

-------------------------------------------------

When numa is used to map CPU to PCI device, the optimized path to read
from cached data is not working and still calls _isst_if_get_pci_dev().

The reason is that when caching the mapping, numa information is not
available as it is read later. So move the assignment of
isst_cpu_info[cpu].numa_node before calling _isst_if_get_pci_dev().
