[SRU][o/n:linux-azure][PATCH 0/1 v2] Revert fix for "Kernel fails to enable XSAVE when running in a “v5” AMD SEV-SNP VM"

[John Cabaj]

BugLink: https://bugs.launchpad.net/bugs/2079841

SRU Justification

[Impact]

* LP #2069204 disabled CET Shadow Stack on SEV-SNP due to CPUID emulation bug 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
