KVM: clarify the idea of kvm_dirty_regs 



This patch clarifies that kvm_dirty_regs are just a hint to the kernel and
that the kernel might just ignore some flags and sync the values (like done for
acrs and gprs now).

Please note that the kernel is allowed to use the kvm_run structure as the

primary storage for certain register types. Therefore, the kernel may use the

values in kvm_run even if the corresponding bit in kvm_dirty_regs is not set.
