Subject: [PATCH 5.13 035/300] crypto: hisilicon/sec - fix the abnormal exiting process

From: Kai Ye <yekai13@...wei.com>

[ Upstream commit 90367a027a22c3a9ca8b8bac15df34d9e859fc11 ]

Because the algs registration process has added a judgment.
So need to add the judgment for the abnormal exiting process.
