bpf: cpumap: make some functions static
Fixes the following sparse warnings: kernel/bpf/cpumap.c:146:6: warning: symbol '__cpu_map_queue_destructor' was not declared. Should it be static? kernel/bpf/cpumap.c:225:16: warning: symbol 'cpu_map_build_skb' was not declared. Should it be static? kernel/bpf/cpumap.c:340:26: warning: symbol '__cpu_map_entry_alloc' was not declared. Should it be static? kernel/bpf/cpumap.c:398:6: warning: symbol '__cpu_map_entry_free' was not declared. Should it be static? kernel/bpf/cpumap.c:441:6: warning: symbol '__cpu_map_entry_replace' was not declared. Should it be static? kernel/bpf/cpumap.c:454:5: warning: symbol 'cpu_map_delete_elem' was not declared. Should it be static? kernel/bpf/cpumap.c:467:5: warning: symbol 'cpu_map_update_elem' was not declared. Should it be static? kernel/bpf/cpumap.c:505:6: warning: symbol 'cpu_map_free' was not declared. Should it be static?
