usb/max3421: fix return error code in max3421_probe()

Browse Source 
[ 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().
