LoongArch: KVM: Fix FPU register width with user access API

Browse source

At the beginning, only 64 bit FPU is supported. With FPU register get
interface, 64 bit FPU data is copied to user space, the same with FPU
register set API. However with LSX and LASX supported in later, there
should be FPU data copied with bigger width. So here fixes this issue,
copy the whole 256 bit FPU data from/to user space.
