dmaengine: fsl-qdma: increase size of 'irq_name'

[ Upstream commit 6386f6c ]

We seem to have hit warnings of 'output may be truncated' which is fixed
by increasing the size of 'irq_name'

drivers/dma/fsl-qdma.c: In function ‘fsl_qdma_irq_init’:
drivers/dma/fsl-qdma.c:824:46: error: ‘%d’ directive writing between 1 and 11 bytes into a region of size 10 [-Werror=format-overflow=]
