    x86: Remove x86 prefixed names from cpuinfo for common.c
    
    struct cpuinfo_x86
      .x86        => .family
      .x86_vendor => .vendor
      .x86_model  => .model
      .x86_mask   => .stepping
    
    No functional change.
    
    This work is part of making Xen safe for Intel family 18/19.
