nested vmx: optimize for bulk access of virtual VMCS
After we use the VMREAD/VMWRITE to build up the virtual VMCS, each
access to the virtual VMCS needs two VMPTRLD and one VMCLEAR to
switch the environment, which might be an overhead to performance.
This commit tries to handle multiple virtual VMCS access together
to improve the performance.
