Subject: [PATCH bpf-next v4 04/12] bpf: selftests: Fix bpf_cpumask_first_zero() kfunc prototype

The prototype in progs/nested_trust_common.h is not in line with how the
actual kfuncs are defined in kernel/bpf/cpumask.c. This causes compilation
errors when kfunc prototypes are generated from BTF.

Fix by aligning with actual kfunc definitions.
