drm/xe/hw_engine_group: Fix potential leak

If we fail to allocate a workqueue we will leak kzalloc'ed group
object since it was designed to be kfree'ed in the drmm cleanup
action, but we didn't have a chance to register this action yet.

To avoid this leak allocate a group object using drmm_kzalloc()
and start using predefined drmm action to release the workqueue.
