    add support for NCQ on Gen IIe hardware

    mvsata_quetag_get()/put() pairs adjusted to work also for non-DMA code paths,
    i.e. during probe; replaced wdcintr() call with local routine which uses
    currently active command tag, rather than assuming always tag 0 on that
    code path

    ~55MB/s -> ~80MB/s sequential read using fio(1) on a test HDD, quite nice
