QAT related bug fixes

Browse Source 
1. Fix issue:  Kernel BUG with QAT during decompression  #9276.
   Now it is uninterruptible for a specific given QAT request,
   but Ctrl-C interrupt still works in user-space process.

2. Copy the digest result to the buffer only when doing encryption,
   and vise-versa for decryption.
