Define sev_enabled and sev_es_enabled as 'false' and explicitly #ifdef
out all of sev_hardware_setup() if CONFIG_KVM_AMD_SEV=n. This kills
three birds at once:
- Makes sev_enabled and sev_es_enabled off by default if
CONFIG_KVM_AMD_SEV=n. Previously, they could be on by default if
CONFIG_AMD_MEM_ENCRYPT_ACTIVE_BY_DEFAULT=y, regardless of KVM SEV
support.
- Hides the sev and sev_es modules params when CONFIG_KVM_AMD_SEV=n.
- Resolves a false positive -Wnonnull in __sev_recycle_asids() that is
currently masked by the equivalent IS_ENABLED(CONFIG_KVM_AMD_SEV)
check in svm_sev_enabled(), which will be dropped in a future patch.
