KVM: SVM: Always print "AVIC enabled" separately, even when force enabled

Print the customary "AVIC enabled" informational message even when AVIC is
force enabled on a system that doesn't advertise supported for AVIC in
CPUID, as not printing the standard message can confuse users and tools.

Opportunistically clean up the scary message when AVIC is force enabled,
but keep it as separate message so that it is printed at level "warn",
versus the standard message only being printed for level "info".
