KVM: SEV: fix compat ABI for KVM_MEMORY_ENCRYPT_OP
The data structs for KVM_MEMORY_ENCRYPT_OP have different sizes for 32- and 64-bit
userspace, but they do not make any attempt to convert from one ABI to the other
when 32-bit userspace is running on 64-bit kernels. This configuration never
worked, and SEV is only for 64-bit kernels so we're not breaking ABI on 32-bit
kernels.
Fix this by adding the appropriate padding; no functional change intended
for 64-bit userspace.
