Oliver Anderson 30063eff7e hypervisor: Include feature MSRs in boot_msr_entries ...

Whenever a CPU profile is selected there will be feature MSRs that need
to be set when the CPU is configured.

We thus adapt the boot_msr_entries method to include the feature MSRs
that are passed to the vCPU upon construction.

Since KVM applies compatibility checks for all feature MSRs (except
IA32_ARCH_CAPABILITIES) we can only proceed if all MSR boot entries
are successfully set upon vCPU configuration.

This new check also applies to the regular boot entries when the host
profile is selected (the default), but that is arguably an improvement
in terms of correctness.
