unix: fix up for "apparmor: add fine grained af_unix mediation"

After merging the apparmor tree, today's linux-next build (x86_64
allmodconfig) failed like this:

security/apparmor/af_unix.c: In function 'unix_state_double_lock':
security/apparmor/af_unix.c:627:17: error: implicit declaration of function 'unix_state_lock'; did you mean 'unix_state_double_lock'? [-Wimplicit-function-declaration]
  627 |                 unix_state_lock(sk1);
      |                 ^~~~~~~~~~~~~~~
