kvm: svm: Fix implicit declaration for __default_cpu_present_to_apicid()

The commit 8221c1370056 ("svm: Manage vcpu load/unload when enable AVIC")
introduces a build error due to implicit function declaration
when #ifdef CONFIG_X86_32 and #ifndef CONFIG_X86_LOCAL_APIC
(as reported by Kbuild test robot i386-randconfig-x0-06121009).

So, this patch introduces kvm_cpu_get_apicid() wrapper
around __default_cpu_present_to_apicid() with additional
handling if CONFIG_X86_LOCAL_APIC is not defined.
