Subject: cxgb4: do not fail vf instatiation in slave mode
Patch-mainline: v4.18-rc1
Git-commit: 7cfac881660ac7b7229950e0a942201be63c15d1
References: bsc#1097585 bsc#1097586 bsc#1097587 bsc#1097588 bsc#1097583 bsc#1097584

We no longer require a check for cxgb4 to be MASTER
when configuring SRIOV, It was required when we had
module parameter to instantiate vf.
