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
