x86/mem_encrypt: Unbreak the AMD_MEM_ENCRYPT=n build
commit 0a9567ac upstream. Moving mem_encrypt_init() broke the AMD_MEM_ENCRYPT=n because the declaration of that function was under #ifdef CONFIG_AMD_MEM_ENCRYPT and the obvious placement for the inline stub was the #else path. This is a leftover of commit 20f07a04 ("x86/sev: Move common memory encryption code to mem_encrypt.c") which made mem_encrypt_init() depend on X86_MEM_ENCRYPT without moving the prototype. That did not fail back then because there was no stub inline as the core init code had a weak function. Move both the declaration and the stub out of the CONFIG_AMD_MEM_ENCRYPT section and guard it with CONFIG_X86_MEM_ENCRYPT.
