x86/kaslr: Avoid the setup_data area when picking location
commit 0cacbfbeb5077b63d5d3cf6df88b14ac12ad584b upstream.
The KASLR location-choosing logic needs to avoid the setup_data
list memory areas as well. Without this, it would be possible to
have the ASLR position stomp on the memory, ultimately causing
the boot to fail.
