Madhuparna Bhowmik cb54984b79 drivers/dma/dma-jz4780: Fix race condition between probe and irq handler 
[ Upstream commit 6d6018fc30bee67290dbed2fa51123f7c6f3d691 ]

In probe, IRQ is requested before zchan->id is initialized which can be
read in the irq handler. Hence, shift request irq after other initializations
complete.

Found by Linux Driver Verification project (linuxtesting.org).
