====================
net: convert atm/xdp/af_iucv/l2tp_ppp/rxrpc/tipc to getsockopt_iter

This series continues the conversion of the remaining proto_ops getsockopt
callbacks to the new getsockopt_iter callback introduced in commit 67fab22a7a
("net: add getsockopt_iter callback to proto_ops").

The new callback takes a sockopt_t — a type-safe wrapper around iov_iter
plus an optlen field — instead of raw __user pointers. This:

    - Replaces (char __user *optval, int __user *optlen) with sockopt_t *opt
    - Reads the input buffer size from opt->optlen instead of get_user()
    - Writes the option value via copy_to_iter() instead of copy_to_user()
    - Reports the returned length via opt->optlen instead of put_user(),
      independently of the bytes copied through the iter

Each conversion is a behaviour-preserving and code-style-preserving refactor;
no big changes being introduced, even when the code looks weird.
