Series bpf: Support dumping kfunc prototypes from BTF | expand

Commit Message

Daniel Xu June 12, 2024, 3:58 p.m. UTC 
The prototype in progs/map_percpu_stats.c is not in line with how the
actual kfuncs are defined in kernel/bpf/map_iter.c. This causes
compilation errors when kfunc prototypes are generated from BTF.

Fix by aligning with actual kfunc definitions.
