[PATCH 16/22] KVM: SVM: Rename svm_flush_tlb() to svm_flush_tlb_current()

[Sean Christopherson <seanjc@google.com>]

Rename svm_flush_tlb() to svm_flush_tlb_current() so that at least one of
the flushing operations in svm_x86_ops can be filled via kvm-x86-ops.h,
and to document the scope of the flush (specifically that it doesn't
flush "all").

Opportunistically make svm_tlb_flush_current(), was svm_flush_tlb(),
static.

No functional change intended.
