KVM: arm64: Reject hyp trace descriptors with fewer CPUs than hyp_nr_cpus
While a trace descriptor with fewer CPUs than hyp_nr_cpus currently
causes no functional issue, such a configuration is invalid and would
cause the hypervisor to skip ring buffer initialization when allocating
backing pages in EL2.
Enforce nr_cpus == hyp_nr_cpus during trace descriptor validation to
guarantee that every possible CPU has a valid ring buffer descriptor.
