riscv: module: Use generic cmp_int() instead of custom cmp_3way()

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.
