Gaosheng Cui eb0f78e28c apparmor: fix a memleak in multi_transaction_new() 
[ Upstream commit c73275cf6834787ca090317f1d20dbfa3b7f05aa ]

In multi_transaction_new(), the variable t is not freed or passed out
on the failure of copy_from_user(t->data, buf, size), which could lead
to a memleak.

Fix this bug by adding a put_multi_transaction(t) in the error path.

Fixes: 1dea3b41e8 ("apparmor: speed up transactional queries")
