CVE-2022-49455

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

misc: ocxl: fix possible double free in ocxl_file_register_afu

info_release() will be called in device_unregister() when info->dev's
reference count is 0. So there is no need to call ocxl_afu_put() and
kfree() again.

Fix this by adding free_minor() and return to err_unregister error path.
