IB/mlx4: Don't call dma_free_coherent() with irqs disabled
mlx4_ib_free_cq_buf() should not be called under spin_lock_irq() since
it calls dma_free_coherent(), which needs irqs enabled. Fix this by
deferring the free to outside the locked region.
This was found due to the
WARN_ON(irqs_disabled());
in swiotlb_free_coherent().
