Vitaly Kuznetsov b26f68c36b i386: HV_HYPERCALL_AVAILABLE privilege bit is always needed 
According to TLFS, Hyper-V guest is supposed to check
HV_HYPERCALL_AVAILABLE privilege bit before accessing
HV_X64_MSR_GUEST_OS_ID/HV_X64_MSR_HYPERCALL MSRs but at least some
Windows versions ignore that. As KVM is very permissive and allows
accessing these MSRs unconditionally, no issue is observed. We may,
however, want to tighten the checks eventually. Conforming to the
spec is probably also a good idea.

Enable HV_HYPERCALL_AVAILABLE bit unconditionally.
