This could mean that your include/generated/autoconf.h, which is used by external modules, is not updated and contains CONFIG_NR_CPUS=8. Do
make mrproper
in your kernel directory by moving your .config out of the way first and then rebuild your kernel and external module(s). nr_cpu_ids should pick up the updated CONFIG_NR_CPUS value from your .config.
