KVM: TDX: Use kvm_arch_vcpu.host_debugctl to restore the host's DEBUGCTL
Use the kvm_arch_vcpu.host_debugctl snapshot to restore DEBUGCTL after
running a TD vCPU. The final TDX series rebase was mishandled, likely due
to commit fb71c7959356 ("KVM: x86: Snapshot the host's DEBUGCTL in common
x86") deleting the same line of code from vmx.h, i.e. creating a semantic
conflict of sorts, but no syntactic conflict.
Using the version in kvm_vcpu_arch picks up the ulong => u64 fix (which
isn't relevant to TDX) as well as the IRQ fix from commit 189ecdb3e112
("KVM: x86: Snapshot the host's DEBUGCTL after disabling IRQs").
