How could the card send DMA completion IRQ before DMA
has finished ?

That definitely sounds like broken hardware and / or firmware
to me...

BTW waiting inside IRQ handler does not sound like a good
real solution to this... perhaps we should poll the device at
regular intervals instead and ask if DMA has finished...
or something like that...
