riscv: remove unreachable invalid range check in kasan_init()
kasan_init() populates the linear mapping shadow with for_each_mem_range()
and breaks the loop when start >= end. for_each_mem_range() never returns
an invalid range, so start < end always.
Therefore the start >= end check is unreachable, so remove it.
No functional change.
