get_dev_pagemap() is only used with CONFIG_ZONE_DEVICE and
USE=kernel-open, and in kernel 6.18 takes one argument in less that
NVIDIA seemingly did not need.
This is a simplified version of 590.44.01's fix which skips the
conftest.sh changes for easier backporting (at worst the simple version
check may break if the kernel backports this to older kernels).
