[PATCH 1/7] KVM: vmx: we do rely on loading DR7 on entry

[Paolo Bonzini <pbonzini@redhat.com>]

Currently, this works even if the bit is not in "min", because the bit is always
set in MSR_IA32_VMX_ENTRY_CTLS.  Mention it for the sake of documentation, and
to avoid surprises if we later switch to MSR_IA32_VMX_TRUE_ENTRY_CTLS.
