[PATCH v2 0/5] drm/xe: Guard against NULL return for xe_device_get_gt

[Jonathan Cavitt <jonathan.cavitt@intel.com>]

In many cases, this can be prevented by using xe_root_mmio_gt instead of
xe_device_get_gt.  Add guards for all other cases.

v2:
- Various commit message fixups (Michal)
- Use xe_assert in xe_guc.c (Michal, Matt)
- Add assert to vf_post_migration_recovery (Michal)
- Modify various xe_pmu functions to take an xe_gt pointer (Michal)
- Fix potential memory leak (Michal)
