Subject: [PATCH 08/16] arch: x86: kernel: Mark internal functions static in kvm.c

kvm.c defines functions kvm_guest_cpu_init and kvm_init_debugfs
internally. No other file defines these, so make them static.

This also eliminates the following warnings:

arch/x86/kernel/kvm.c:334:6: warning: no previous prototype for ‘kvm_guest_cpu_init’ [-Wmissing-prototypes]
arch/x86/kernel/kvm.c:658:16: warning: no previous prototype for ‘kvm_init_debugfs’ [-Wmissing-prototypes]
