David Matlack 37ef0be269 KVM: nVMX: Add tracepoint for nested VM-Enter
Call trace_kvm_nested_vmenter() during nested VMLAUNCH/VMRESUME to bring
parity with nSVM's usage of the tracepoint during nested VMRUN.

Attempt to use analagous VMCS fields to the VMCB fields that are
reported in the SVM case:

"int_ctl": 32-bit field of the VMCB that the CPU uses to deliver virtual
interrupts. The analagous VMCS field is the 16-bit "guest interrupt
status".

"event_inj": 32-bit field of VMCB that is used to inject events
(exceptions and interrupts) into the guest. The analagous VMCS field
is the "VM-entry interruption-information field".

"npt_enabled": 1 when the VCPU has enabled nested paging. The analagous
VMCS field is the enable-EPT execution control.

"npt_addr": 64-bit field when the VCPU has enabled nested paging. The
analagous VMCS field is the ept_pointer.
