IB/ipoib: Add child to parent list only if device initialized

From: Valentine Fatiev <[email protected]>

Despite failure in ipoib_dev_init() we continue with initialization flow and creation of child device. It causes to the situation where this child device is added too early to parent device list.

change the logic, so in case of failure we properly return error from ipoib_dev_init() and add child only in success path.

Fixes eaeb39842508 ("IB/ipoib: Move init code to ndo_init")
