Huaitong Han e24ed5519f kvm: x86: Fix vmwrite to SECONDARY_VM_EXEC_CONTROL 
commit 45bdbcfdf241149642fb6c25ab0c209d59c371b7 upstream.

vmx_cpuid_tries to update SECONDARY_VM_EXEC_CONTROL in the VMCS, but
it will cause a vmwrite error on older CPUs because the code does not
check for the presence of CPU_BASED_ACTIVATE_SECONDARY_CONTROLS.

This will get rid of the following trace on e.g. Core2 6600:

vmwrite error: reg 401e value 10 (err 12)
Call Trace:
