[PATCH] apparmor: Fix checking address of an array in accum_label_info()

[Nathan Chancellor]

clang warns:

  security/apparmor/label.c:206:15: error: address of array 'new->vec' will always evaluate to 'true' [-Werror,-Wpointer-bool-conversion]
    206 |         AA_BUG(!new->vec);
        |                ~~~~~~^~~

The address of this array can never be NULL because it is not at the
beginning of a structure. Convert the assertion to check that the new
pointer is not NULL.

Fixes: de4754c801f4 ("apparmor: carry mediation check on label")
