KVM: x86: Drop now-redundant MAXPHYADDR and GPA rsvd bits from vCPU creation 

Drop the manual initialization of maxphyaddr and reserved_gpa_bits during
vCPU creation now that kvm_arch_vcpu_create() unconditionally invokes
kvm_vcpu_after_set_cpuid(), which handles all such CPUID caching.

None of the helpers between the existing code in kvm_arch_vcpu_create()
and the call to kvm_vcpu_after_set_cpuid() consume maxphyaddr or
reserved_gpa_bits (though auditing vmx_vcpu_create() and svm_vcpu_create()
isn't exactly easy).
