SRU Justification
[Impact]

not being fixed in VMs until October 2024.
* This issue is now fixed, so the patch can be reverted.
[Fix]
* Revert "UBUNTU: SAUCE: x86/hyperv: temporarily disable CET SS on
SEV-SNP due to a paravisor bug"
[Test Plan]
* Compile tested
* Boot tested
[Regression potential]
* Reverting back to previous state, so regression very unlikely.
* Changes isolated, minimal regression risk
[Other info]
* SF #00387447
