[PATCH][HIRSUTE][RESEND] UBUNTU: SAUCE: apparmor: Fix build error, make sk parameter const

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

Make the sk parameter const to fix a build error with clang:

security/apparmor/net.c:143:35: error: passing 'const struct sock *' to
parameter of type 'struct sock *' discards qualifiers
[-Werror,-Wincompatible-pointer-types-discards-qualifiers]
                        audit_unix_sk_addr(ab, "addr", sa->u.net->sk);
                                                       ^~~~~~~~~~~~~
/home/ubuntu/hirsute/security/apparmor/net.c:98:24: note: passing argument
to parameter 'sk' here
                               struct sock *sk)
                                            ^
