target/loongarch: Fix [X]VLDI raising exception incorrectly
According to the specification, [X]VLDI should trigger an invalid instruction
exception only when Bit[12] is 1 and Bit[11:8] > 12. This patch fixes an issue
where an exception was incorrectly raised even when Bit[12] was 0.
Test case:
```
.global main
main:
vldi $vr0, 3328
ret
```
