[PATCH v3 2/2] usb: chipidea: ci_hdrc_imx: Fix error handling when creating IRQ name

[phucduc.bui at gmail.com]

From: bui duc phuc <phucduc.bui at gmail.com>

devm_kasprintf() can fail when allocating the wakeup IRQ name. The error
was logged with dev_err_probe(), but its return value was ignored and
probe could continue with a successful return value.

Store the error returned by dev_err_probe() in ret and jump to the error
path to propagate the failure.
