Routine Description:

    This routine removes the pages that relocate and debug information from
    the address space of the driver.

           header and if that section is marked as DISCARDABLE in the
           characteristics, it is removed from the image.  This means
           that all discardable sections at the end of the driver are
           deleted.

Return Value:
