net/mlx5e: Fix capability check for updating vnic env counters
[ Upstream commit 452133dd580811f184e76b1402983182ee425298 ]
The existing capability check for vnic env counters only checks for
receive steering discards, although we need the counters update for the
exposed internal queue oob counter as well. This could result in the
latter counter not being updated correctly when the receive steering
discards counter is not supported.
Fix that by checking whether any counter is supported instead of only
the steering counter capability.
