[PATCH] drm/xe: sysfs_ops needs to be defined on parent directory

[Tejas Upadhyay]

Currently, xe_hw_engine_sysfs_kobj_type is defining sysfs_ops
on wrong directory. Sysfs_ops needs to be defined on immediate
parent directory to be able to called on each attribute set/get.

Fixes: 3f0e14651ab0 ("drm/xe: Runtime PM wake on every sysfs call")
