KVM: arm64: avoid unused-variable warning

Browse source

The 'cpu' variable is only used inside of an #ifdef block and causes
a warning if there is no user:

arch/arm64/kvm/hyp_trace.c: In function 'kvm_hyp_trace_init':
arch/arm64/kvm/hyp_trace.c:422:13: error: unused variable 'cpu' [-Werror=unused-variable]
  422 |         int cpu;
      |             ^~~

Change the #ifdef to an equivalent IS_ENABLED() check to avoid
the warning.
