crypto: mv_cesa - ensure backlog is initialised

Browse source 
backlog is not initialised so in the case where
cpg->eng_st != ENGINE_IDLE it is never initialised and
hence which could lead to an illegal memory dereference
in the statement:

  backlog->complete(backlog, -EINPROGRESS);

Discovered with cppcheck static analsys:
[drivers/crypto/mv_cesa.c:616]:
   (error) Uninitialized variable: backlog
