usb: imx21-hcd: fix error return code in imx21_probe()
[ Upstream commit 46edf52d08342b3dc1f9a61c5200ab8b1c0f5a37 ]
platform_get_irq() returns an error code, but the imx21-hcd 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 error message and propagate the return value of platform_get_irq
on failure.
This issue was detected with the help of Coccinelle.
