Subject: IB/mlx4: Fix ib device initialization error flow

From: Jack Morgenstein <[email protected]>

commit 99e68909d5aba1861897fe7afc3306c3c81b6de0 upstream.

In mlx4_ib_add, procedure mlx4_ib_alloc_eqs is called to allocate EQs.

However, in the mlx4_ib_add error flow, procedure mlx4_ib_free_eqs is not called to free the allocated EQs.

Fixes e605b743f33d ("IB/mlx4: Increase the number of vectors (EQs) available for ULPs")
