    Ensure the result of MGAMapMem is checked.
    
    Add GCC warn_unused_result attribute to MGAMapMem.  Add a check of the
    return value to one place that was missing it (in MGACountRam), and
    check the return of that function.

    Refactor memory map / unmap functions.
    
    MGAMapMem and MGAMapMemFBDev were refactored into a single function.
    This happens to fix a bug triggered in software XAA paths because
    MGAMapMem did not set FbStart.  MGAUnmapMem and MGAUnmapMemFBDev were
    also refactored into a single function.
