x86/kvm: Remove unused virt to phys translation in kvm_guest_cpu_init()

Presumably, this was introduced due to a conflict resolution with
commit ef68017eb570 ("x86/kvm: Handle async page faults directly through
do_page_fault()"), given that the last posted version [1] of the blamed
commit was not based on the aforementioned commit.
