CVE-2022-50245

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

rapidio: fix possible UAF when kfifo_alloc() fails

If kfifo_alloc() fails in mport_cdev_open(), goto err_fifo and just free
priv. But priv is still in the chdev->file_list, then list traversal
may cause UAF. This fixes the following smatch warning:

drivers/rapidio/devices/rio_mport_cdev.c:1930 mport_cdev_open() warn: '&priv->list' not removed from list
