sev_config currently has debug, ghcbs_initialized, and use_cas fields. However, __reserved count has not been updated. Fix this.

Fixes: 34ff65901735 ("x86/sev: Use kernel provided SVSM Calling Areas") Cc: stable@vger.kernel.org

stable because?

Thanks for noticing this.

I shall remove Cc tag since: 1. The commit that introduced the bug is only part of 6.11-rc1. So there is no stable kernel fix needed here. 2. An incorrect __reserved field did not cause any hang/data corruption or a build-error.

I will re-spin a v2.

Thanks, Pavan
