When userspace is debugging guest then MSR_DE is always set and MSRP_DEP is set so that guest cannot change MSR_DE. Guest debug resources are not yet emulated, So there seems no reason we should stop guest controlling MSR_DE. Also a followup patch will enable debug emulation and that requires guest to control MSR_DE.
