KVM: selftests: Fix KVM_EXCEPTION_MAGIC build with Clang
Change KVM_EXCEPTION_MAGIC to use the all-caps "ULL", rather than lower
case. This fixes a build failure with Clang:
In file included from x86_64/hyperv_features.c:13:
include/x86_64/processor.h:825:9: error: unexpected token in argument list
return kvm_asm_safe("wrmsr", "a"(val & -1u), "d"(val >> 32), "c"(msr));
^
include/x86_64/processor.h:802:15: note: expanded from macro 'kvm_asm_safe'
asm volatile(KVM_ASM_SAFE(insn) \
^
include/x86_64/processor.h:785:2: note: expanded from macro 'KVM_ASM_SAFE'
"mov $" __stringify(KVM_EXCEPTION_MAGIC) ", %%r9\n\t" \

<inline asm>:1:18: note: instantiated into assembly here
mov $0xabacadabaull, %r9
