spi/bcm63xx: fix error return code in bcm63xx_spi_probe()
platform_get_irq() returns an error code, but the spi-bcm63xx 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.
