KVM: VMX: more cleanups to __vmx_vcpu_run

Browse source

Slightly improve register allocation, loading vmx only once
before vmlaunch/vmresume.

This also makes the code slightly more similar to the one for
AMD processors, in that both keep the pointer to struct vcpu_vmx
or vcpu_svm in %rdi.  The code for restoring the guest value of
SPEC_CTRL is also the same for Intel and AMD.
