kernel test robot reported the warning below:

  >> net/core/filter.c:11842:13: warning: declaration of 'struct bpf_tcp_req_attrs' will not be visible outside of this function [-Wvisibility]
      11842 |                                         struct bpf_tcp_req_attrs *attrs, int attrs__sz)
            |                                                ^
     1 warning generated.

struct bpf_tcp_req_attrs is defined under CONFIG_SYN_COOKIES
but used in kfunc without the config.

Let's move struct bpf_tcp_req_attrs definition outside of
CONFIG_SYN_COOKIES guard.
