  x86/sev: Remove redundant ghcbs_initialized checks around __sev_{get,put}_ghcb() (2026-05-19 13:31:29 -0700)

----------------------------------------------------------------
- Remove redundant GHCB initialization guards in the SEV page state and SVSM
  call paths now that the GHCB helpers handle early-boot fallback internally

- Skip SNP initialization in the CCP driver immediately when the preparation
  step fails rather than proceeding to an operation that will certainly fail

- Abort SNP preparation and return an error when not all CPUs are online,
  since the firmware enforces that every CPU enables SNP and will fail init if
  not

- Simplify the VMM communication exception entry path by replacing separate
  kernel and user mode macros with a single handler that dispatches based on
  the current privilege level
