crypto: mv_cesa - ensure backlog is initialised
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
