dmaengine: ipu: remove bogus NO_IRQ reference

Browse Source 
A workaround for a warning introduced a use of the NO_IRQ
macro that should have been gone for a long time.

It is clear from the code that the value cannot actually
be used, but apparently there was a configuration at
some point that caused a warning, so instead of just
reverting that patch, this rearranges the code in a way that
the warning cannot reappear.
