    x86/pagewalk: Address MISRA R8.3 violation in guest_walk_tables()
    
    Commit 4c5d78a10dc8 ("x86/pagewalk: Re-implement the pagetable walker")
    intentionally renamed guest_walk_tables()'s 'pfec' parameter to 'walk' 
because
    it's not a PageFault Error Code, despite the name of some of the constants
    passed in.  Sadly the constants-cleanup I've been meaning to do since then
    still hasn't come to pass.
    
    Update the declaration to match, to placate MISRA.
    
    Fixes: 4c5d78a10dc8 ("x86/pagewalk: Re-implement the pagetable walker")
