[PATCH AUTOSEL for 4.14 09/60] crypto: lrw - Fix an error handling path in 'create()'

[alexander . levin]

From: Christophe Jaillet <christophe.jaillet@xxxxxxxxxx>

[ 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.

Fixes: 700cb3f5fe75 ("crypto: lrw - Convert to skcipher")
