selftests: kvm: move declaration at the beginning of main()
Placing a declaration of evt_reset is pedantically invalid
according to the C standard. While GCC does not really care
and only warns with -Wpedantic, clang ignores the declaration
altogether with an error:
x86_64/xen_shinfo_test.c:965:2: error: expected expression
struct kvm_xen_hvm_attr evt_reset = {
^
x86_64/xen_shinfo_test.c:969:38: error: use of undeclared identifier evt_reset
vm_ioctl(vm, KVM_XEN_HVM_SET_ATTR, &evt_reset);
^
