Subject: [PATCH net-next 3/7] net/mlx4_core: Fix misleading debug print on CQE stride support

From: Or Gerlitz <ogerlitz@...lanox.com>

We do support cache line sizes of 32 and 64 bytes without activating the
CQE stride feature. Fix a misleading print saying that these cache line
sizes aren't supported.
