Subject: s390/qeth: fix race when initializing the IP address table
Git-commit: 7221b727f0079a32aca91f657141e1de564d4b97
Patch-mainline: v5.1-rc3
References: bsc#1051510

The ucast IP table is utilized by some of the L3-specific sysfs attributes
that qeth_l3_create_device_attributes() provides. So initialize the table
_before_ registering the attributes.

Fixes: ebccc7397e4a ("s390/qeth: add missing hash table initializations")
