bpf: fix implicit declaration of bpf_prog_add
For the ifndef case of CONFIG_BPF_SYSCALL, an inline version of
bpf_prog_add needs to exist otherwise the build breaks on some configs.
drivers/net/ethernet/mellanox/mlx4/en_netdev.c:2544:10: error: implicit declaration of function 'bpf_prog_add'
prog = bpf_prog_add(prog, priv->rx_ring_num - 1);
The function is introduced in
59d3656d5bf50 ("bpf: add bpf_prog_add api for bulk prog refcnt")
and first used in
47f1afdba2b87 ("net/mlx4_en: add support for fast rx drop bpf program").
Fixes: 47f1afdba2b87 ("net/mlx4_en: add support for fast rx drop bpf program")
