crypto: user - Fix crypto_alg_match race
The function crypto_alg_match returns an algorithm without taking
any references on it. This means that the algorithm can be freed
at any time, therefore all users of crypto_alg_match are buggy.
This patch fixes this by taking a reference count on the algorithm
to prevent such races.
