Continue to convert the protocols to getsockopt_iter callback.

Proto llcp is one of the last to be converted, and it was waiting for
the following fixes to land first, avoiding merge conflicts.

 * commit 000fb5bc757a ("nfc: llcp: read llcp_sock->local under the
   socket lock in getsockopt")
 * commit 81e676dec04f4 ("nfc: llcp: avoid userspace overflow on invalid
   optlen")

Now that they have landed, let's move llcp to .getsockopt_iter callback

Regarding the whole project migration, this is where we are:
