mm/memremap: avoid calling kasan_remove_zero_shadow() for device private memory
For device private memory, we do not create a linear mapping for the
memory because the device memory is un-accessible. Thus we do not add
kasan zero shadow for it. So it's unnecessary to do
kasan_remove_zero_shadow() for it.
