[PATCH rdma-next 1/2] IB/mlx4: Fix ib device initialization error flow

[Leon Romanovsky <leon-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>]

From: Jack Morgenstein <jackm-LDSdmyG8hGV8YrgS2mwiifqBs+8SCbDb@public.gmane.org>

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")
