drm/amdkfd: fix sysfs kobj leak

Browse source

[ Upstream commit dcdb4d904b ]

3 cases of kobj leak, which causes memory leak:

kobj_type must have release() method to free memory from release
callback. Don't need NULL default_attrs to init kobj.

sysfs files created under kobj_status should be removed with kobj_status
as parent kobject.

Remove queue sysfs files when releasing queue from process MMU notifier
release callback.
