Currently, KASAN on LoongArch assume the CPU VA bits is 48, which is true for Loongson-3 series, but not for Loongson-2 series (only 40 or lower), this patch fix that issue and make KASAN usable for variable cpu_vabits. Solution is very simple: Just define XRANGE_SHADOW_SHIFT which means valid address length from VA_BITS to min(cpu_vabits, VA_BITS).
