KVM: nVMX: Check for pending INIT/SIPI after entering non-root mode
Explicitly check for a pending INIT or SIPI after entering non-root mode
during nested VM-Enter emulation, as no VMCS information is quered as part
of the check, i.e. there is no need to check for INIT/SIPI while vmcs01 is
still loaded.
