[ 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.
