Revert "KVM: nVMX: move check_vmentry_postreqs() call to nested_vmx_enter_non_root_mode()"

This reverts commit 7392aa08f8a4386c99d5c6506a79e2ccd5b4701f which is
commit 7671ce21b13b9596163a29f4712cb2451a9b97dc upstream.

It should not have been selected for a stable kernel as it breaks the
nVMX regression tests.
