[PATCH bpf-next v4 06/12] bpf: selftests: Fix bpf_session_cookie() kfunc prototype

[Daniel Xu]

The prototype defined in bpf_kfuncs.h was not in line with how the
actual kfunc was defined. This causes compilation errors when kfunc
prototypes are generated from BTF.

Fix by aligning with actual kfunc definition.
