sw64: kvm: fix size of struct kvm_regs for C3B 

Sunway inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/IBDJNZ



--------------------------------

The size of struct kvm_regs passed by Qemu is fixed and checked
in kernel. Since Qemu has extended the struct kvm_regs, this patch
adds some padding bytes to ensure that the size of struct kvm_regs
is the same on both C3B and C4.
