IB/mlx4: Fix ib device initialization error flow
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")
