dmaengine: idxd: Avoid unnecessary destruction of file_ida

CVE-2024-38629

Description

In the Linux kernel, the following vulnerability has been resolved:

file_ida is allocated during cdev open and is freed accordingly during cdev release. This sequence is guaranteed by driver file operations. Therefore, there is no need to destroy an already empty file_ida when the WQ cdev is removed.

Worse, ida_free() in cdev release may happen after destruction of file_ida per WQ cdev. This can lead to accessing an id in file_ida after it has been destroyed, resulting in a kernel panic.

Remove ida_destroy(&file_ida) to address these issues.
