[PATCH] KVM: Unexport kvm_debugfs_dir

[PATCH] KVM: Unexport kvm_debugfs_dir

[Borislav Petkov]

From: "Borislav Petkov (AMD)" <bp@alien8.de>

After

  faf01aef0570 ("KVM: PPC: Merge powerpc's debugfs entry content into generic entry")

kvm_debugfs_dir is not used anywhere else outside of kvm_main.c

Unexport it and make it static.
