[reactos] 03/03: [FASTFAT] While closing FCBs on dismount, release from tail to head and not the contrary. It fixes assertion failure in vfatDestroyFCB() where we would have release parent before child. This is still not perfect, but less bug prone...

    [FASTFAT] While closing FCBs on dismount, release from tail to head and not the
contrary.
    It fixes assertion failure in vfatDestroyFCB() where we would have release parent
before child.
    This is still not perfect, but less bug prone...
    
    With this commits (and ENABLE_SWAPOUT defined), ReactOS seems to unmount FAT volumes
quite nice! :-)
    (Tried with fsutil volume dismount X:)
