Subject: [PATCH 5.2 130/135] net/mlx5e: Remove redundant check in CQE recovery flow of tx reporter

From: Aya Levin <ayal@...lanox.com>

[ Upstream commit a4e508cab623951dc4754f346e5673714f3bbade ]

Remove check of recovery bit, in the beginning of the CQE recovery
function. This test is already performed right before the reporter
is invoked, when CQE error is detected.

Fixes: de8650a82071 ("net/mlx5e: Add tx reporter support")
