apparmor: fix NULL sock in aa_sock_file_perm
In the Linux kernel, the following vulnerability has been resolved: apparmor: fix NULL sock in aa_sock_file_perm Deal with the potential that sock and sock-sk can be NULL during socket setup or teardown. This could lead to an oops. The fix for NULL pointer dereference in __unix_needs_revalidation shows this is at least possible for af_unix sockets. While the fix for af_unix sockets applies for newer mediation this is still the fall back path for older af_unix mediation and other sockets, so ensure it is covered.
