QAT driver checks byte alignment for KASUMI/SNOW 3G/ZUC algorithms using
cipher/auth_param, which are not initialized at this moment yet. Use
operation params instead.

Change in v2 :
- fixed implementation to avoid data truncation
This fix should be backported to stable.
In 18.08 the code location has changed.
In earlier releases it was
in qat_write_hw_desc_entry() in qat/qat_crypto.c
