This is a matter of preference. I intentionally chose to drop mem_enc part
because actually KVM_MEMORY_ENCRYPT_OP is abused for TDX or SEV(-SNP) specific
operation. Subcommand for KVM_MEMORY_ENCRYPT_OP is not directly related to
memory encryption. It should be KVM_CONFIDENTIAL_OP or something.
Unfortunately it's too late to rename it.
