Pan Bian e5bde04ccc crypto: do not free algorithm before using 
In multiple functions, the algorithm fields are read after its reference
is dropped through crypto_mod_put. In this case, the algorithm memory
may be freed, resulting in use-after-free bugs. This patch delays the
put operation until the algorithm is never used.

Fixes: a7d85e06ed ("crypto: cfb - add support for Cipher FeedBack mode")
