fix more leaks in audit_tree.c tag_chunk()
Several leaks in audit_tree didn't get caught by commit 318b6d3d7ddbcad3d6867e630711b8a705d873d7, including the leak on normal exit in case of multiple rules refering to the same chunk. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
