Michal Swiatkowski cd8a34cbc8 pfcp: avoid copy warning by simplifing code 
From Arnd comments:
"The memcpy() in the ip_tunnel_info_opts_set() causes
a string.h fortification warning, with at least gcc-13:

    In function 'fortify_memcpy_chk',
        inlined from 'ip_tunnel_info_opts_set' at include/net/ip_tunnels.h:619:3,
        inlined from 'pfcp_encap_recv' at drivers/net/pfcp.c:84:2:
    include/linux/fortify-string.h:553:25: error: call to '__write_overflow_field' declared with attribute warning: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Werror=attribute-warning]
      553 |                         __write_overflow_field(p_size_field, size);"

It is a false-positivie caused by ambiguity of the union.

However, as Arnd noticed, copying here is unescessary. The code can be
simplified to avoid calling ip_tunnel_info_opts_set(), which is doing
copying, setting flags and options_len.

Set correct flags and options_len directly on tun_info.

Fixes: 6dd514f481 ("pfcp: always set pfcp metadata")
