In a regular interrupt handler driver was finishing the crypt/decrypt
request by calling complete on crypto request. This is disallowed since
converting to skcipher in commit
b286d8b1a690 ("crypto: skcipher - Add
skcipher walk interface") and causes a warning:
WARNING: CPU: 0 PID: 0 at crypto/skcipher.c:430 skcipher_walk_first+0x13c/0x14c
The interrupt is marked shared but in fact there are no other users
sharing it. Thus the simplest solution seems to be to just use a
threaded interrupt handler, after converting it to oneshot.
