x86/sev: Guard sev_evict_cache() with CONFIG_AMD_MEM_ENCRYPT
The sev_evict_cache() is guest-related code and should be guarded by
CONFIG_AMD_MEM_ENCRYPT, not CONFIG_KVM_AMD_SEV.
CONFIG_AMD_MEM_ENCRYPT=y is required for a guest to run properly as an SEV-SNP
guest, but a guest kernel built with CONFIG_KVM_AMD_SEV=n would get the stub
function of sev_evict_cache() instead of the version that performs the actual
eviction. Move the function declarations under the appropriate #ifdef.
Fixes: 7b306dfa326f ("x86/sev: Evict cache lines during SNP memory validation")
