    x86/svm: Rename arch_svm_struct to svm_vcpu
    
    The suffix and prefix are redundant, and the name is curiously odd.  Rename 
it
    to svm_vcpu to be consistent with all the other similar structures.  In
    addition, rename local arch_svm local variables to svm for further
    consistency.
    
    No functional change.
