net/mlx5: Fix driver load bad flow when having fw initializing timeout

net/mlx5: Fix driver load bad flow when having fw initializing timeout

[ 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.
