LoongArch: Make KASAN usable for variable cpu_vabits
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).
