drm/xe/hw_engine_group: Avoid call kfree() for drmm_kzalloc()
Memory allocated with drmm_kzalloc() should not be freed using kfree(), as it
is managed by the DRM subsystem. The memory will be automatically freed when
the associated drm_device is released.
These 3 group pointers are allocated using drmm_kzalloc() in hw_engine_group_alloc(),
so they don't require manual deallocation.
