From: Chenghai Huang <huangchenghai2@huawei.com>

[ Upstream commit c9ccfd5e0ff0dd929ce86d1b5f3c6a414110947a ]

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.
