kernel/auditfilter: kill bogus uninit'd-var compiler warning
Kill this warning... kernel/auditfilter.c: In function ‘audit_receive_filter’: kernel/auditfilter.c:1213: warning: ‘ndw’ may be used uninitialized in this function kernel/auditfilter.c:1213: warning: ‘ndp’ may be used uninitialized in this function ...with a simplification of the code. audit_put_nd() can accept NULL arguments, just like kfree(). It is cleaner to init two existing vars to NULL, remove the redundant test variable 'putnd_needed' branches, and call audit_put_nd() directly. As a desired side effect, the warning goes away.
