[PATCH] apparmor: use the condition in AA_BUG_FMT even with debug disabled

[Mateusz Guzik <mjguzik@gmail.com>]

This follows the established practice and fixes a build failure for me:
security/apparmor/file.c: In function ‘__file_sock_perm’:
security/apparmor/file.c:544:24: error: unused variable ‘sock’ [-Werror=unused-variable]
  544 |         struct socket *sock = (struct socket *) file->private_data;
      |                        ^~~~

Plausibly the sock var wants to be eliminated altogether, but I just
want this to build.
