SRU Justification

[Impact]

* When running stress-ng race-sched portion of ubuntu_stress_smoke_test, a NULL
  pointer dereference occurs on Azure Standard_A2_v2 instances with 100% reproducibility

[Fix]

* Clean cherry-pick from upstream
* Commit 1560d1f6eb6b398bddd80c16676776c0325fe5fe "sched/eevdf: Prevent vlag from going out of bounds in reweight_eevdf()"

[Test Plan]

* Compile tested
* Boot tested
* Tested on Standard_A2_v2 instance, experienced panic without patch, successful
  test with patch

[Regression potential]

* Changes isolated, minimal regression risk
