phonet: pep: convert getsockopt to sockopt_t

Continue converting the proto-layer getsockopt callbacks to the
sockopt_t interface, splitting pep_getsockopt() into a
do_pep_getsockopt() helper that takes a sockopt_t.

The thin pep_getsockopt() wrapper keeps its __user signature for now:
it builds a user-backed sockopt_t with sockopt_init_user(), calls the
helper, and writes the returned length back to optlen. The helper uses
copy_to_iter() instead of copy_to_user(). No functional change.
