Subject: crypto: inside-secure - move cipher crypto mode to request context
Git-commit: 847ccfc5866950873b20c6fd980808f6043061ae
Patch-mainline: v4.16-rc1
References: fate#326470
The cipher direction can be different for requests within the same
transformation context. This patch moves the direction flag from the
context to the request scope.
