Strings associated with virDomainHyperv values in domain_conf.c are used to construct HyperV CPU features names to be compared with names defined in cpu_x86_data.h and the names for HyperV "spinlocks" feature don't match. This leads to a misleading warning: "host doesn't support hyperv 'spinlocks' feature" even when it's supported. Let's fix it and rename along with it VIR_CPU_x86_KVM_HV_SPINLOCK to VIR_CPU_x86_KVM_HV_SPINLOCKS.
