Subject: [PATCH 4.9 28/54] net/mlx5: Fix driver load bad flow when having fw initializing timeout

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Mohamad Haj Yahia <mohamad@...lanox.com>


[ Upstream commit 55378a238e04b39cc82957d91d16499704ea719b ]

If FW is stuck in initializing state we will skip the driver load, but
current error handling flow doesn't clean previously allocated command
interface resources.

Fixes: e3297246c2c8 ('net/mlx5_core: Wait for FW readiness on startup')
