Revert "nSVM: Check for reserved encodings of TLB_CONTROL in nested VMCB"
Revert KVM's made-up consistency check on SVM's TLB control. The APM says
that unsupported encodings are reserved, but the APM doesn't state that
VMRUN checks for a supported encoding. Unless something is called out
in "Canonicalization and Consistency Checks" or listed as MBZ (Must Be
Zero), AMD behavior is typically to let software shoot itself in the foot.
This reverts commit 174a921b6975ef959dd82ee9e8844067a62e3ec1.
