    Subjectthat stupid aic7xxx AHC_NSEGS bug
    From

    We simply forget to initialize scb->sg_count in the non use_sg
    case, so if the previous usage of that scb has sg_count==AHC_NSEGS
    then we'd hit that panic erroneously. Here is the fix below.

    "It can't possibly be my driver, something broke in some Linux
    subsystem which is making my driver break", sheesh get over it
