gpu: host1x: fix error return code in host1x_probe()

platform_get_irq() returns an error code, but the host1x driver
ignores it and always returns -ENXIO. 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.
