[PATCH v3 2/8] LoongArch: remove unreachable invalid range check in kasan_init()

[Sang-Heon Jeon <ekffu200098@gmail.com>]

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.
