sh: dma: fix request_irq usage

When calling request_irq with IRQF_SHARED, the dev cookie must be set
(i.e. non-NULL), otherwise the code rejects it immediately with -EINVAL.
So restore the logic here where we'd pass a pointer to the name as a
dummy unique val.

Otherwise, booting up on my LANDISK system would fail with:
	DMAC Address Error0 request_irq fail

This was introduced in commit 7f47c7189b3e8f19a589f77a3ad169d7b691b582.
