Subject: ethtool: don't fall back to grxfhindir when context was specified
Patch-mainline: v4.16
Git-commit: 7984d34ea893a529330b6addb959cbf6e3ec026f
References: fate#326122 bsc#1105557

In do_grfxh(), if rss_context is non-zero, we must not fall back to
 do_grxfhindir() if ETHTOOL_GRSSH fails, for that reads the default RSS
 context and not the one specified.

Fixes: f5d55b967e0c ("ethtool: add support for extra RSS contexts and RSS steering filters")
