Subject: [PATCH] crypto: ccree - fix missing break in switch statement
Add missing break statement in order to prevent the code from falling
through to case S_DIN_to_DES.
This bug was found thanks to the ongoing efforts to enable
-Wimplicit-fallthrough.
Fixes: 63ee04c8b491 ("crypto: ccree - add skcipher support")
