Subject: crypto: lrw - Fix an error handling path in 'create()'

From: Christophe Jaillet <christophe.jaillet@wanadoo.fr>


[ Upstream commit 616129cc6e75fb4da6681c16c981fa82dfe5e4c7 ]

All error handling paths 'goto err_drop_spawn' except this one.
In order to avoid some resources leak, we should do it as well here.
