[ Upstream commit 5a569343e8a618dc73edebe0957eb42f2ab476bd ]
retval may be reassigned to 0 after max3421_of_vbus_en_pin(),
if allocate memory failed after this, max3421_probe() cann't
return ENOMEM, fix this by moving assign retval afther max3421_probe().
Fixes: 721fdc83b31b ("usb: max3421: Add devicetree support")
