[PATCH v4 1/2] Split out struct kvmppc_vcore creation to separate function

[Stewart Smith <stewart@linux.vnet.ibm.com>]

No code changes, just split it out to a function so that with the addition
of micro partition prefetch buffer allocation (in subsequent patch) looks
neater and doesn't require excessive indentation.
