Subject: [PATCH 5/5] KVM: x86: Clean up redundant pr_fmt(fmt) macro definition for svm

From: Like Xu <likexu@...cent.com>

The svm specific pr_fmt(fmt) macro is repeatedly defined in svm code
and the new one has never been used outside the svm context.

Let's move it to svm.h without any intended functional changes.
