Subject: [PATCH 9/9] crypto: hisilicon/debugfs - Add the err memory release process to qm uninit

When the qm uninit command is executed, the err data needs to
be released to prevent memory leakage. The error information
release operation and uacce_remove are integrated in
qm_remove_uacce.

So add the qm_remove_uacce to qm uninit to avoid err memory
leakage.
