drive mirror:fix memory leak
In the function mirror_iteration() -> qemu_iovec_init(), it allocates memory for op->qiov.iov, when the write request calls back, but in the function mirror_iteration_done(), it only frees the op, not free the op->qiov.iov, so this causes memory leak. It should use qemu_iovec_destroy() to free op->qiov. Signed-off-by: Zhang Min <rudy.zhangmin@huawei.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
