bpf: Fix sparse warning for bpf_kptr_xchg_proto
Kernel Test Robot complained about missing static storage class
annotation for bpf_kptr_xchg_proto variable.
sparse: symbol 'bpf_kptr_xchg_proto' was not declared. Should it be static?
This caused by missing extern definition in the header. Add it to
suppress the sparse warning.
Fixes: c0a5a21c25f3 ("bpf: Allow storing referenced kptr in map")
