KVM: VMX: Wrap all accesses to IA32_DEBUGCTL with getter/setter APIs
commit 7d0cce6cbe71af6e9c1831bff101a2b9c249c4a2 upstream.
Introduce vmx_guest_debugctl_{read,write}() to handle all accesses to
vmcs.GUEST_IA32_DEBUGCTL. This will allow stuffing FREEZE_IN_SMM into
GUEST_IA32_DEBUGCTL based on the host setting without bleeding the state
into the guest, and without needing to copy+paste the FREEZE_IN_SMM
logic into every patch that accesses GUEST_IA32_DEBUGCTL.
No functional change intended.
