Merge: arch/x86/kernel/setup.c: fix rh_check_supported

MR: https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-9/-/merge_requests/6428

JIRA: https://issues.redhat.com/browse/RHEL-71452



Upstream Status: RHEL only

When in kdump we don't need any messaging about deprecated status.
The kernel is limited to a single cpu single cpu by default
which causes false messaging to show every time.

Fix this by inverting the kdump boot test. To get proper
messaging during standar boot.
