[PATCH iproute2-next] bash-completion: devlink: fix port param name show completion

[Saeed Mahameed <saeed@kernel.org>]

From: Saeed Mahameed <saeedm@nvidia.com>

Port param names are found with "devlink port param show", and not
"devlink param show", fix that.

Port dev name can be a netdev, so find the actual port dev before
querying "devlink port params show | jq '... [$dev] ...'",
since "devlink port params show" doesn't return the netdev name,
but the actual port dev name.
