Hangyu Hua ee89d8dee5 misc: ocxl: fix possible double free in ocxl_file_register_afu 
[ Upstream commit 950cf957fe34d40d63dfa3bf3968210430b6491e ]

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.
