arm64: KVM: Add braces to multi-line if statement in virtual PMU code
The kernel is written in C, not python, so we need braces around
multi-line if statements. GCC 6 actually warns about this, thanks to the
fantastic new "-Wmisleading-indentation" flag:
| virt/kvm/arm/pmu.c: In function ‘kvm_pmu_overflow_status’:
| virt/kvm/arm/pmu.c:198:3: warning: statement is indented as if it were guarded by... [-Wmisleading-indentation]
| reg &= vcpu_sys_reg(vcpu, PMCNTENSET_EL0);
| ^~~
| arch/arm64/kvm/../../../virt/kvm/arm/pmu.c:196:2: note: ...this ‘if’ clause, but it is not
| if ((vcpu_sys_reg(vcpu, PMCR_EL0) & ARMV8_PMU_PMCR_E))
| ^~
As it turns out, this particular case is harmless (we just do some &=
operations with 0), but worth fixing nonetheless.
