bnxt_en: ethtool: Supply ntuple rss context action

[ Upstream commit be75cda92a65a13db242117d674cd5584477a168 ]

Commit 2f4f9fe5bf5f ("bnxt_en: Support adding ntuple rules on RSS
contexts") added support for redirecting to an RSS context as an ntuple
rule action. However, it forgot to update the ETHTOOL_GRXCLSRULE
codepath. This caused `ethtool -n` to always report the action as
"Action: Direct to queue 0" which is wrong.

Fix by teaching bnxt driver to report the RSS context when applicable.
