    Since commit b009031f ("KVM: PPC: Book3S HV: Take out virtual
    core piggybacking code", 2016-09-15), we only have at most one
    vcore per subcore.  Previously, the fact that there might be more
    than one vcore per subcore meant that we had the notion of a
    "master vcore", which was the vcore that controlled thread 0 of
    the subcore.  We also needed a list per subcore in the core_info
    struct to record which vcores belonged to each subcore.  Now that
    there can only be one vcore in the subcore, we can replace the
    list with a simple pointer and get rid of the notion of the
    master vcore (and in fact treat every vcore as a master vcore).
    
    We can also get rid of the subcore_vm[] field in the core_info
    struct since it is never read.
