target/loongarch: Fix the vinsgr2vr/vpickve2gr instructions cause system coredump

Browse Source 
The vinsgr2vr/vpickve2gr instructions need use get_src/get_dst to get
gpr registers value, not cpu_gpr[]. The $zero register does not
have cpu_gpr[0] allocated.

Resolves: https://gitlab.com/qemu-project/qemu/-/issues/1662
