The module-sections.c file defines a custom cmp_3way() macro to perform
3-way comparisons during relocation sorting.

Instead of maintaining our own implementation, use the generic
cmp_int() macro provided by the already included <linux/sort.h>. This
removes redundant code and relies on standard kernel interfaces.

Thanks, queued for v7.2.  Looks like arm, arm64, and loongarch have the 
same problem.  Care to fix those too (in separate patches)?
