Subject: [PATCH] net/i40e: fix TM level capability getting

[ upstream commit 0d0f144831b24d5b54a75631de9f6c5b9074b4ce ]

Only queue nodes should be taken as leaf nodes, all
the other nodes are non-leaf nodes.
Correct it when getting the TM level capability.

Fixes: 0fb1ef1e7930 ("net/i40e: support getting TM level capability")
