    docs: correct "gnttab=" documented default
    
    Defaults differ for Arm and x86, not the least because of v2 not even
    being security supported on Arm.
    
    Also drop a bogus sentence from gnttab_max_maptrack_frames, which was
    presumably mistakenly cloned from gnttab_max_frames (albeit even there
    what is being said is neither very precise nor very useful imo).
