    x86: constify local variables in mapcache_current_vcpu()
    
    As of the referenced commit v won't be returned from the function anymore.
    Yet that was the sole reason for it to not be pointer-to-const. curr,
    which was introduced by that change, had no reason to be pointer-to-non-
    const from the start.

loaded")
