dmaengine: pl330: Clear callback_result for re-used descs
The pl330 driver re-uses DMA descriptors rather than reallocating
them each time. At present, upon re-use the .callback member is
cleared, but .callback result is not. This causes problems where a
consuming driver sets the .callback_result for some submissions but
not for others, as eventually the function is invoked erronously.
Clear .callback_result along with .callback
