[PATCH 0/2] KVM: x86: Cleanup kvm_get_dr() usage

[Sean Christopherson <seanjc@google.com>]

Make kvm_get_dr() use an actual return instead of a void return with an
output, which led to a _lot_ of ugly code, and then open code all direct
reads to DR6 and DR7, as KVM has a goofy mix of some flows open coding
reads and some flows bouncing through kvm_get_dr().
