[PATCH 1/2] x86/pagewalk: Address MISRA R8.3 violation in guest_walk_tables()

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

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.
