Subject: crypto: inside-secure - free requests even if their handling failed

From: "Antoine T�nart" <antoine.tenart@free-electrons.com>


[ Upstream commit 0a02dcca126280595950f3ea809f77c9cb0a235c ]

This patch frees the request private data even if its handling failed,
as it would never be freed otherwise.
