uio_pdrv_genirq: Remove warning when irq is not specified

Browse Source 
commit 324ac45f25e634eca6346953ae531e8da3e0c73d upstream.

Since e3a3c3a20555 ("UIO: fix uio_pdrv_genirq with device tree but no
interrupt"), the uio_pdrv_genirq has supported use without interrupt,
so the change in 7723f4c5ecdb ("driver core: platform: Add an error
message to") added false warnings for those cases.

Fixes: 7723f4c5ecdb ("driver core: platform: Add an error message to platform_get_irq*()")
