Subject: [PATCH] KVM: Replace DEFINE_SIMPLE_ATTRIBUTE with DEFINE_DEBUGFS_ATTRIBUTE

Fix the following coccicheck warning:

./arch/x86/kvm/debugfs.c:44:0-23: WARNING: vcpu_tsc_scaling_frac_fops
should be defined with DEFINE_DEBUGFS_ATTRIBUTE.

./arch/x86/kvm/debugfs.c:36:0-23: WARNING: vcpu_tsc_scaling_fops should
be defined with DEFINE_DEBUGFS_ATTRIBUTE.

./arch/x86/kvm/debugfs.c:27:0-23: WARNING: vcpu_tsc_offset_fops should
be defined with DEFINE_DEBUGFS_ATTRIBUTE.
