Now that the per-VM, on-demand allocation logic in kvm_setup_gdt() and
vcpu_init_descriptor_tables() is gone, fold them into vcpu_init_sregs().
Note, both kvm_setup_gdt() and vcpu_init_descriptor_tables() configured the
GDT, which is why it looks like kvm_setup_gdt() disappears.
Opportunistically delete the pointless zeroing of the IDT limit (it was
being unconditionally overwritten by vcpu_init_descriptor_tables()).
