The value "new" is being assigned to NULL but that statement does not
have effect since "new" is being overwritten in the subsequent
fallback case.
Remove the unused value. This issue was reported by coverity static
analyzer.
Fixes: a9eb185be84e9 ("apparmor: fix x_table_lookup when stacking is not the first entry")
