usb: musb: musbhsdma: fix IRQ check
dma_controller_create() in this MUSB DMA driver only regards 0 as a wrong IRQ
number, despite platform_get_irq_byname() that it calls returns -ENXIO in that
case. It leads to calling request_irq() with a negative IRQ number, and when it
naturally fails, the following is printed to the console:
request_irq -6 failed!
and the DMA controller is not created.
Fix this function to filter out the error values as well as 0.
