mmc: mxcmmc: fix error return code in mxcmci_probe()
platform_get_irq() returns an error code, but the mxcmmc driver
ignores it and always returns -EINVAL. This is not correct,
and prevents -EPROBE_DEFER from being propagated properly.
Print error message and propagate the return value of
platform_get_irq on failure.
