Subject: [PATCH 5.6 049/118] net/mlx5e: Fix q counters on uplink representors

From: Roi Dayan <roid@...lanox.com>

[ Upstream commit 67b38de646894c9a94fe4d6d17719e70cc6028eb ]

Need to allocate the q counters before init_rx which needs them
when creating the rq.

Fixes: 8520fa57a4e9 ("net/mlx5e: Create q counters on uplink representors")
