Use kvm_x86_ops.cache_reg() in ept_update_paging_mode_cr0() rather than

This sentence does not parse because it's not a proper sentence.
Only one generation of CPU, Nehalem, supports EPT but not
unrestricted guest, and disabling unrestricted guest without also
disabling EPT is, to put it bluntly, dumb.
This one is only significantly better and lacks an explanation what this
means for the dumb case.
Well, it means a retpoline (see paragraph before). However, I'm not
sure why it one wouldn't create a vt.h header with all vt_* functions.
