    x86/srat: fix end calculation in nodes_cover_memory()
    
    Along the lines of commit 7226486767 ("x86/srat: fix the end pfn check
    in valid_numa_range()") nodes_cover_memory() also doesn't consistently
    use "end": It's set to an inclusive value initially, but then compared
    to the exclusive "end" field of struct node and also possibly set to
    nodes[j].start, making it exclusive too. Change the initialization to
    make the variable consistently exclusive.
