usb: dwc3: omap: fix error return code in dwc3_omap_probe()

[ Upstream commit 0ae99ecb ]

platform_get_irq() returns an error code, but the dwc3-omap driver
ignores it and always returns -EINVAL. This is not correct and,
prevents -EPROBE_DEFER from being propagated properly.

Notice that platform_get_irq() no longer returns 0 on error:

Print and propagate the return value of platform_get_irq on failure.

This issue was detected with the help of Coccinelle.
