KVM: SVM: Rename init_vmcb_after_set_cpuid() to make it intercepts specific

KVM: SVM: Rename init_vmcb_after_set_cpuid() to make it intercepts specific

Rename init_vmcb_after_set_cpuid() to svm_recalc_intercepts_after_set_cpuid()
to more precisely describe its role.  Strictly speaking, the name isn't
perfect as toggling virtual VM{LOAD,SAVE} is arguably not recalculating an
intercept, but practically speaking it's close enough.

No functional change intended.
