mshv-ioctls: Don't initialize partition after creation

Instead, we should let VMM decide when it wants to initialize the
partition. For example, for an ARM64 guest VMM needs to setup GIC params
before the partition is initialized. Because the GIC params are early
partition properties which can only be set before the partition is
initialized.

In general since MSHV considers a distinction between partition creation
vs partition initialization, we should reflect the same in our APIs and
not club together into a single function.
