bpf: Fix sparse warning for bpf_kptr_xchg_proto

Browse source

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: c0a5a21c25 ("bpf: Allow storing referenced kptr in map")
